So, enough people have given you the stereotypical "leave your sanity"
What you need to know is that I will be your ruler, you will heed my orders and you will be off fine...
On a serious note, basically just have fun and be yourself, the place is full of different personalities whether you like it or not and I'm sure you'll fit in one way or another. I'm usually open to chat myself if you'd like, and could answer any questions you may have, so don't be afraid to PM me for stuffs.
Another thing you can do to really solidify a home for you here is to sign up for PokeNations, this will give you a chance to really get to know some people, and just have a blast on the server, competitive or not.
Except if you get placed into Apophyll
I guess I stress that you should really take part on the different events we have here, whether it be tournaments, the PokeNations, a fap contest, you name it. It's really your best bet into the ideal Reborn experience.....trademark
Bottom Line, don't be afraid to have fun
