I guess you could say TBU is the group that sponerst the server. Getting member in TBU will get you respected/member on any of the groups servers. But getting respected on the PNRP server (Or the Minecraft Server) does not mean you have group membership.
These forums here are not directly tied to TBU, even though all the Dev's and admins here are in TBU. This site is dedicated to the development of projects for Radioactive Cricket.
http://radioactivecricket.com/Currently our main project is PostNukeRP, thats why pretty much all the chatter is about that.
Eventually there will be sections for CyberPunkRP, the Headcrab Gamemode, and other various projects by out Dev group.
