2 things:

It'd be nice to have the ability to spam the wait list to a channel (officer, guild or an arbitrary channel) so that others can see who is on the list. It would also be nice to allow players to remove themselves from the wait list by sending "!waitlist remove" or something similar and check who is on the wait list via "!waitlist who". I'm not sure about other guilds but we used a mod called EKWaitList to keep track of the list. It had some nice features (such as the ones above) that would work nicely in GRSS.

Secondly, when answering a DKP Review Request I'd like to be able to provide a response along with the Approval/Denial.

Both good ideas.
