I have a suggestion that I believe would greatly increase the accessibility of the forum, especially for those who really appreciated the email list format.
If there were a section on the home page that listed the 10 most recently posted/commented threads, or all new threads/comments within the last 24 hours, users would be able to see at a glance what conversations are currently live. It would function similarly to the B-Greek Digest. Right now, seeing that X user posted something in a forum isn't particularly helpful.
Here are some forums (fora?) that employ a similar idea:http://sharperiron.org/foundryhttp://www.puritanboard.com/forum/
Of course, I have no idea how difficult or expensive such a change would be. Is it feasible?
