Captain Calle basically summed it up. But to clarify a little more.
When you play
on eGO servers you
MUST have the beginning part of your name look like this:
=(e)=? kotahlicious
you can however add ending tags.
Example:
=(e)=? kotahlicious [esg]
=(e)=? kotahlicious [S|R]
=(e)=? kotahlicious [RFC]*
If these are just groups, friends, DOD houses, etc. then you can add them on the end no big deal, but the beginning part must always be the same. HOWEVER: If these are another clan, that require you to put your tag at the beginninging.
Example:
[ESG] kotahlicious
Then you can only do so when you play on
NON-eGO servers. And should change your name
(ie: removing the (e) tag) BEFORE you enter any servers, and must change it back when you enter an eGO server.
There is nothing wrong, or anything against the rules about doing this. Just know that while you wear the eGO tag you represent us all, and so must always follow our rules no matter what server you play.
