One of the things I thought could be implemented, was a more 'passive' way to tell if somebody is online or not. For example, I believe the original iteration of the forum had a sort of light in the bottom left corner of a user's post, with a green light indicating they were online, and no light equating to offline/invisible. I do know you can hover over a username to read when/where a poster's last activity was, but I just thought it'd help for when we receive an influx of posters. Thanks!
