Well, lets give the mods/HQ some time to put the rules together. They did make a huge change so they might be busy. Until then, lets go with the trial and error method. Post whatever you want to post and if it is against the rules, I'm sure Matt would send you a PM right away.
Maybe it's just me but they had the forums down for quite some time; I would have thought that HQ would have had the ability to put the rules together in that time.
I don't think trial and error is really the best way to go about this, especially when they're handing out warnings for a new rule that hasn't been elaborated on too much. I know that real life political discussion is not permitted, however, is discussing the account of a player that is named after a prominent political figure permissible? What if I wanted to mention that that player's wall was getting destroyed? Or that they keep getting attacked by an alliance that is named after another prominent political figure? Would I even be allowed to have put the names of the players in this example?
