The leaderboard is broken.

When exporting a rich format document in the writing tab into the message board, bold formatting specifically is broken and results in broken BBCode.
Page URL: virtual.aopsacademy.org/class/<any writing class works here>/writing

TO REPRODUCE
1. enter "Lorem ipsum".
2. apply bold to "Lorem"
3. apply italic to "ip".
4. click the Post Draft on Message Board
5. read the contents of the message board post.

FOR EXAMPLE
When I format "Lorem ipsum" (in the writing tab of course), but when I export to post it, I get

Lorem[/b] [i]ip[/i]sum

.

Notice that the first bolding does not start, only ends.

In my AOPS class, there are points on your report where your red bar turns orange, and your orange turns green, well my orange bar passed the small green mark but the bar did not turn green. I can't take a screenshot, but my orange bar should be green according to the color marking.

How did this happen? Has anyone else had this?

I already submitted an extension but I cannot edit it because I submitted an unfinished solution. I have not viewed the solution.

As outlined in this (locked) post, the forum/blog creation message is out of date. It has been over a year since that post, and it still has not changed. I don't know if this got lost somewhere in the "passing this along" chain or if it was determined to be irrelevant, but it seems like a relatively simple fix
