well, I already have a very small erp guild on an alliance server in the US format. Had it before I participated in this discussion. I mentioned the 18 because the games started shutting down erp guilds if they didn't take care about that...And I am sooo not into doing erp with minors. As the matter of fact, I set up on the new server and guild because I had family, to include minors, on the other server and did not even want them to accidental trip across an erp situation.
If anyone wants a home and is discrete, mine is welcoming members PM me It is new, small and growing. We have death knights starting at 55 for those with higher level characters on other servers. And baby alts for other classes of interest.
Warning, my guild leader death knight has a night elf Death Knight pet protector who loves to see her date others. She can get pretty aggressive.
But I am currently intrigued with some things to be found in Elliquiy and am hoping that there is a growing group of people that are comfortable roaming there and seeing me when I go..or setting up a scene time with me there.
