Forums

What do the stars under my username next to a forum post represent?

On the Art of Problem Solving website, under your username, you will find stars, as well as the name of one of the Millenium Problems. The number of stars you have, as well as the name of the Millenium Problem, depends on your post count. Here is the table that determines your "rank."

• 0 - 19 New Member (Zero Stars)
• 20 - 49 P versus NP (Half Star)
• 50 - 99 Hodge Conjecture (One Star)
• 100 - 249 Poincare Conjecture (Two Stars)
• 250 - 499 Riemann Hypothesis (Two and Half stars)
• 500 - 999 Yang Mills Theory (Three Stars)
• 1000 - 2499 Navier-Stokes Equation (Four Stars)
• 2500 - Birch & Swinnerton Dyer. (Five Stars)
• Administrators have six stars.

I got the message "You can not post at this time" when trying to post, why?

New users are not allowed to post messages with URLs and various other things. Once you have five posts you can post normally.

If I make more posts, it means I'm a better user, right?

Absolutely not. Post quality is far more important than post quantity. Users making a lot of senseless posts are often considered worse users, or spammers.

I have made some posts but my post count did not increase. Why?

When you post in some of the forums, such as the Test Forum, Mafia Forum, and the Fun Factory, it does not count towards your post count.

Who can see my post rating?

Only you, moderators, and administrators.

How does AoPS select moderators?

When a new moderator is needed in the forums, AoPS administrators first check if any current moderators could serve as a moderator of the forum which needs a moderator. Should none be found, AoPS administrators and/or other moderators scour the forum looking for productive users. They may also ask for suggestions from other moderators or trusted users on the site. Once they have pinpointed a possible candidate based on their long term usage of the site, productive posts in the forum, and having no recent behavioral issues, that user is asked if he or she would like to moderate the forum.

Less active forums often have no moderator. Inappropriate posts should be reported by users and administrators will take appropriate action.

AoPS receives MANY requests to be a moderator. As they receive so many, it is possible that you won't get a response should you request to be one. Also, AoPS very rarely makes someone a mod for asking to be one, so please do not ask.

I believe a post needs corrective action. What should I do?

If you believe a post needs moderative action, you may report it by clicking the "!" icon on the bottom-right corner of that post. If it's a minor mistake, you may want to PM the offending user instead and explain how they can make their post better. Usually, you shouldn't publicly post such things on a thread itself, which is called "backseat moderation" and is considered rude.

How long of a non-commented thread is consider reviving?

If any post is still on-topic and isn't spammy or anything, it isn't considered reviving. The definition of reviving in the Games forum is 1 month. However, everyone has a different period of time that they consider reviving. In general, apply common sense.

Someone is marking all my posts as spam, what should I do?

It happens to everyone. There's really not much you can do.

Are posts marked spam more often than good?

No. The most common rating is 6 cubes. We understand that many posts are rated 1 when they shouldn't be. We also know that many posts are rated a 6 when they shouldn't be. It pretty much all averages out in the end. The best way to safeguard yourself is not to complain about it! In fact, most other members cannot see your rating. If you want to make a mark here, let your post quality do the talking.

How do I post images?

There are limited attachment options for posts. Attachments have an overall size limit, and will be deleted as the get old. Attachments also may be deleted during any server move or software upgrade or change. You may instead wish to host images on another site and embed them in to your post using the [img] tags. The general format is [img]{url to image}[/img], excluding the braces. There are a number of image hosting sites, including:

• Imgur
• Photobucket

• In thumbnail view

• Hover over image and click the text box labeled IMG code. It will automatically copy to your clipboard
• Paste to your message

• In image view

• Look for the Links box which should appear at the right side of your screen

• Paste to your message

• ImageShack

• Click the share tab
• Copy the contents of the Forum Code text

School

What if I want to drop out of a class?

For any course with more than 2 classes, students can drop the course any time before the third class begins and receive a full refund. No drops are allowed after the third class has started. To drop the class, go to the My Classes section by clicking the My Classes link at the top-right of the website. Then find the area on the right side of the page that lets you drop the class. A refund will be processed within 10 business days.

Are there any audio and video during class?

There is no audio or video in the class. The classes are completely text based, in an interactive chat room environment, which allows students to ask questions at any time during the class. In addition to audio and video limiting interactivity, the technology isn't quite there yet for all students to be able to adequately receive streaming audio and video.

I feel like joining! What are my class choices?
