Welcome back.
There are many social linkshells on this server. Usually these shells are not overly occupied with endgame activities. However this game is 8 years old and almost all the existing players have a job at 75 or higher.
I belong to a nice social/helpful linkshell called Shibby. The people in this linkshell will welcome you. If you need help with your whitemage AF pieces and limit breaks, you will have no problem finding help from this shell. Almost everyone in Shibby is a sackholder. This way they can all invite new people to the shell.
I don't have much opportunity to play except on the weekends, but here are a few of the sackholders who play more than I do. Just send a tell and say Daffney said I could get a pearl.
Mrpinchy, Ziplock, Killie, Solan, Gatelord, Ebrim, Domasbob, Korthos, Senara, Terasul, Deathsoul, Hagbart, Walsh, Shmoopie
