Oh, well, this was unexpected... to have a new player take interest in the RP while the Compendium with all the background information is unavailable, that is. I would recommend either waiting until the Compendium is back in working order before starting to make your characters in detail, or I suppose you could just ask for the information you need (generally you can ask about anything, and I'll try to supply a satisfactory reply).
Eh, but in case it wasn't clear from what I just said, feel free to submit a character for review. Having a suitable character is really the only requirement for being admitted into the RP.
