Here is one more in support!

Most importantly we need to be able to kick those who have permanently quit. I have one member in my linkshell who quit the game, forgot to retire his pearl, and completely deactivated his SE account. He realized after the fact about forgetting to retire the pearl, but now he can't even access his character to do so (for lack of active account), but no one can kick his character from the shell either. Positively ridiculous!

Linkshell Message would be pretty nice, too.
