I agree wholeheartedly with the OP.
I really do hope the dev team will raise this issue because these options are fundamental for all linkshell administrators. (should have been already implemented quite a while ago)
As a linkshell creator/leader it saddens me to see 30+ ls members that are fundamentally ghosts just taking up space..
Please SE have plans for this after the battle system has been updated!
(and please consider adding a mail system to enhance communications ect since this IS an mmo!) ((thank you))
