3 years? I think somebody forgot to set that alarm clock!
Welcome back, mate! I'm sorry to hear about your friends and your guild going AWOL, but it happens to all of us at one time or another, aye?
These here forums are flooded with hundreds of great pirates and guilds from all over the Caribbean. I highly suggest looking around these parts for a new crew to pair up with
As for advice, I suggest jumping at the Grenade quest (if you haven't already done so) and pounding away at grenade levels. It may get boring at first, but... it'll be for your better in the long run
If you need anything else, just PM me, or any of the other wonderful people that lurk around here.
Happy pirating!
