ok, i was just thinking about the jail system + a event back in the days i GM'ed on a lineage2 server.
in newadmin you set the jail location and than jail people. I was thinking maybe you guys could setup somthing like !setarena size and !arena name to put them in.
just somthing that could be kinda fun, like have it strip and block q menu from them people put into arena, admin give them the weapons that will be used and maybe setup some cover and ya.
