Red Dawn is the only guild that groups as they level on a wide scale, so they're a safe bet and would welcome you in.
There's always a shortage of clerics if you're in the mood to start one. I wrote a solo cleric guide which is on the wiki (but more with the blue server in mind as it includes Unrest). Wizard/necro would give you the solo ability... SKs seem popular here, you'd be in good company.
Overall roll whatever you feel in the mood to play, and enjoy the experience... there's still an XP bonus compared to blue and its quicker to level, but it isn't as high as it was over the thanksgiving weekend.
You can chat in global /ooc at Level 10. Get involved or switch it off, your choice
