I don't exactly have any fancy bumps or know how to make them, but I can pop in from time to time and post random things and talk with people to get the thread cruising at the top of the page. I'm a writer, so I could post small, one paragraph stories. It would give something interesting for people to read and talk about. If you have any slots still open, I'm generally free on weekends and sporadically throughout the week due to classes. You said that you'd like for us to start posting at 6am Eastern time, but what about the cut-off time? 7pm? 10pm? I'm in the Central time zone myself, but I do tend to stay up late because of studying. I usually use chat rooms or forums as a backdrop while I study anyways (instead of t.v. or music), so being a bumper shouldn't be too difficult. I know it seems counter productive, but it actually helps get my brain going and ideas flowing.
