how do you want to solve the trust abusing problems in there? ... will your admins be members you personally know from rl only? ...
else you probably will have moles n liars in there, too, who will play their role perfectly over months even (too many corruptable ppl in this world ... greed makes it possible) ... and break your neck ...
nothing new, is it? ...
now ... when I once was embarrassed about some harmingly twisted facts by PARTS of my pms shown around behind my back (p for "private" btw) no one cared or wasted a single thought on this and what this means to gameplay in general to trust ANYONE in such a game ... ... I got called dumb only just bc I dared communicating ... I still do though btw ... any kind of "private" chat won't change much either as long as you can't keep it private anyway ... and when you trust the wrong and get betrayed you'll be called dumb in the end, too, only ... but mistrusting isn't helpful either ... solve that ... can you? ... I can't ...
dk if it makes any difference ... but granting my support though ... it may(!) help for wars at least ...
