I'm not really a fan of rep systems just because they make people feel bad unnecessarily. If someone breaks forum rules then they get in trouble, but if you just have personal disagreements with someone, then it doesn't mean they deserve to have that displayed on their profile in public and have it affecting their forum rep for everyone to see. Negative rep doesn't really serve any purpose besides making people feel bad. Plus people would want to dispute negative rep and how the staff decide if it was worthy of a negative or not? I wouldn't mind a positive rep system only, I guess, which would eliminate most of the problems I listed. Let's see what everyone else thinks.

The PM scheduling/a reminder system sounds good, but I'm not sure if a mod exists for that. I haven't been able to find anything. If anyone finds one that looks suitable, let me know! :D
