I honestly see no need for new admins, at least EU1 is fine. Most of the time when I play, which is "early evening", there is at least one admin on. No idea how active they are admin'ing while playing but I do see Ujin quite often lately and Tenne too actually.
There is a pink text now and then, sometimes a kick for leeching... seems good to me. Though I should probably add that I don't see everything that serious and therefore may not be the wisest suggestion for adminship:
1 TK isn't ruining the fun for everyone!
1 leecher isn't ruining the fun for everyone!
1 naked guy w/o weapon dies rather instantly on EU1 and again, isn't ruining the fun for everyone!
...but maybe I am one of the few who doesn't really care about a lost pixel-life in a gamemode where you have infinite respawns
Just talking about EU1 since I do not play Siege or DTV.
