I've come across this scenario too many times. Even www.moodle.org has this problem, a page with a long list of forums in it. Unfortunately, this page has to be in the center column of the course because inside a course, forums can only be added in the center column, not in blocks.
One way of changing this would be the ability to insert new forums inside resource pages. One could then create a complete page full of forums and describe them properly with headings etc.
Chardelle has created a block which allows users to add forums into blocks inside a course. While this is handy, it still doesnt solve the issue of not sowing all the forum names on the main page of the course.
I would like to work towards this, does anyone have ideas or suggestions or a simple hack to get this done ?
