Have to agree with making forums more user friendly, could have simple things like "Search within forum" to limit the results. I wanted to find postings about efficient ways to set up forums for grading. Either I have to look through so many discussion topics in the Forum forum, page after page hunting for one that might be relevant, or I use the search forums feature. I typed in "Grading Forums" and of course all those words were in your post. It is not helpful to find what I'm looking for.
There are such simple things that could make Moodle so much better. Open Source has its benefits for sure, but it is frustrating to be a teacher trying to use this program.
