My (vague) understanding is that back when this thread was created, UniLang was intended to be used as some kind of online university, so maybe this was supposed to be a French course that was part of that. However, the forum that was also part of UniLang ended up becoming by far the most popular part of UniLang, so maybe some of the old courses were moved to the forum so that people could ask any burning questions they had about anything there, or something like that. The rest of these courses I believe are in the "resource archive."
I don't know how much of this I may have gotten wrong (all of it??
), so I hope somebody who knows about all this better comes along and gives you a better answer.
