I do not know if the forum has the structure needed for something like that. There are thousands of other structures much better prepared.
I dont agree with that. Many years ago, I learned how to play poker on a forum, and a made good money as a result. There are other educational forums about finances as well. I think a forum; well-structured it is an ideal place for those courses. You can have articles and videos and structure them in different levels, where you can't unlock the next level if you haven't passed the previous one.
I quite like Theymos idea.
