Hey Bfroger, nice to meet you. I'm pretty new here myself, only being a member here for a few days.
Since I seem to be the first one to greet you, let me see if I can tell you what the others tell everyone else.
Welcome to Reborn, not many people here seem to think sanity is needed, but I've kept mine anyways. You already seem to know about the server and have played the game, so I don't think I need to tell you much about those. There's quite a few people to ask if you have any questions or concerns, a few notable people would include Vinny and Sheep, but I'll also try to help as well.
I'm not a competitive battler myself, but if you are, feel free to check out the Hall of Nations subforum, which can be found above the Grand Hall.
There's also a section for Roleplaying down near the bottom. Hakuna is the one you want to talk to for that.
As for anything else, feel free to explore the forums yourself and join in the community.
There, that's all I can think of at the moment, if I missed anything someone else will come in and mention it. Enjoy your stay.
