Hey, Silly Underground Family are active and recruiting, loads of long time EU players, Killer Bee has made a recruitment thread here that you can check out.
Well I have been active in hunting Oratans and Oro's on Arkadia. I am a miner by trade though...just hunting to turn a few cycles while waiting for AH. I have seen that these Soc's are recruiting: Deus Vult and The Friendly Dragons. There are a few others who are recruiting in Rookie Chat too.
