I like all the stuff on the left side of everyone's post but I find it very annoying when I'm scrolling through a large thread and some relatively short responses make the thread unnessisarily longer. I don't know what exactly can be done about that. I guess I would suggest getting rid of the box that contains AIM contact info and what not could just be gotten rid of. I mean, when I want to contact someone on any message board, I just look in their profile for available means of contacting them.
Also, instead of putting a "check" link underneath how many credits you have, you could make the number of credits you have the link itself. Also, if someone has a trader rating of 0 make it so it doesn't show up. Alright, now I'm out of ideas.
