It would be nice to have the ability to have forums (or even threads) that are limited access to a specific clan only. These forums would be a good way to share clan information (game critiques, performance reports, etc.) without having to fill everyone's mail box with messages.
To avoid hopeless clutter on the Forum's area, the clan-specific forum of a given clan would only be visible to the members of a that clan.
Would anyone else like to see this feature? Technically, it should not be too hard to implement (this is a guess as I have no idea what kind of platform the site is built on...)
