I have now completed my sub-admin system, and I'll release it soon as part of the Jk2 1.02 Admin Mod for windows.
Features I've completed(so far) are:
*Sub-Admin system
*Kill command
*centerprint command (The character '|' is replaced with a new line)
*rename command (Currently the new name must contain no spaces)
*am_nochat cvar (If set to 1, no one on the server can use chat, team_chat, or private chat)
I will probably release this mod (version 1) within a week or two.
I'm currently working on:
*Fixing the rcon status bug
* New admin features for JK2Ded 1.02E
