Current FOCS class has active discussion forum, and Prof. Goldschmidt and some mentors are interested in embedding Overleaf or some open source module to support Latex in discussion forum better.

Please feel free to add ideas..

EDITED TO ADD:

Implementation finished in PR #11931
But we need to add simple example latex markdown to our documentation page:
https://submitty.org/student/communication/markdown

Close issue when documentation is finished.
