Since tonight armathentication authority at crazy-tronners.com has been changed. Users shouldn't feel a big difference - we still log in using username@ct, but now the deamon picks up a group assigned to You by CT staff. This means server will no longer recognize users as @ct.
Following above CT division consist of 5 groups:
1. TrialMembers@ct/trial
2. JuniorCTers@ct/junior
3. SeniorCTers@ct/senior
4. Leaders@ct/leader
5. ServerTechs@ct/jedi
+ 6. NonCTers@ct/public for all other board users.
Administrators are pelased to change their servers authentication configurations files so ACCESS_LEVELs of users@ct points to users@ct/group. If You're not sure what group the user belongs to - ask on #armagetron @ irc.freenode.net ".ctgroups username" and tronner will answer You. (link) On sumo "/cmd ctgroups username" will give you the same information. Also a browser is available.

bottom line for those that don't understand:

if you like to authenticate you don't have to change anything. yournick@ct will work. no changes there. you'll just notice that once you're logged in you've been assigned to some special group. for example if you're not a clan member you'll get yournick@ct/public or drug addicted server techs get yournick@ct/jedi etc...
