One feature that used to exist was that a tiny avatar of the last poster appeared beside each Topic heading in the “Recently active topics”. You could then see if anyone had responded to your last post without actually clicking on the topic. If you saw your own avatar, there were (obviously) no further updates. If there was an easy way to bring that back, that would be great.
Another discussion is that the front page needs to be updated. Josh did a great job when originally throwing up the site, but it would be neat to have some of our groups awesome photos on the front page at the top. The text could use a bit of refreshing as well, although there will probably be much debate on the exact text to be used.
