If controlling Linkshell management within the game itself is "too difficult", then why not implement it through the Lodestone? The Lodestone already operates as an interface for viewing game statistics online and includes the ability to view Linkshell memberships, utilizing these memberships to provide access and post within a Linkshell's own personal forum of sorts.

It would not be a huge extention to develop this interface further. Furthermore, it would take at least some of the workload for this task away from the UI team and relegate it to the Web/Lodestone team.

I'm sure there are other ideas outside the box as well.
