I have a 100+ member linkshell and find it really difficult to try to organize any kind of events or leave any notifications, best I'm able to do atm is notify people logged on at the moment and hope word spreads. Would be so much simpler if we could leave a simple message of the day or comment for linkshell members.
Also, with so many members it is nigh impossible to keep track of who is no longer active and who is only semi-active. A status of when each member last logged in would help immensely when trying to remove inactive members.
