@Silent: We need it in plugins. That's the only possible way now. Talk to Cannon if you need help, he's already done 3.
@Keshi: I am not very sure what stuff you want to list. Stuff on other players? Don't think it's a good idea. We've got scanners for that, they work on different ranges and this would sort of kill that area. Regarding the max player limit, it's hardcoded and it's 200.
