I'd just like to take a minute to apologize for the slowness of getting this latest change (the Role-based raid signups) deployed. Admittedly, this proved to be a slightly more daunting task than I originally planned.
On those lines how about the scheduling module that has been discussed? Just to refresh this was the idea of providing a place for users to input their normal schedule of availability by weekday and times which would allow us to see what (or how many) people are available when scheduling an event.
