Hello mate. I should let you know that linkshells are kind of warry of those returning players. I bet the LS you had on when you left you didn't think to yourself "hey, i'm going to leave, I better drop my LS". Most left it on, and this means that slots of the LS were filled but inactive. A LOT of ls's were created, and recreated just becasue it was full of people who no longer play with no means of kicking them..

I'd suggest camping behest, doing some leves, and trying to make friends, and see if someone you speak with will give you an LS. Random invites of people with no history is rare!
