Hey, another guy brought up from the Stygian gloom of lulwuttery into the shining world of decent arpee above. Read the rules. Familiarize yourself with the principles of arpee. Be productive. Welcome aboard. Oh, and a tip: old factions don't necessarily equate to good factions. Investigate any you're interested in thoroughly before doing anything else.
....and I would advize you have a lot of solo practice with RP. Factions can be really picky about RP as they are SUPPOSED to set the example of how people should act on here.
