Rapid Raid Attendance tracking

Hi .. I think I'm having a blonde moment.

One of the ranks we have in our guild is reserved for those who raid with us on a *fairly* regular basis.  Only I'm a bit dim and kinda forget, over the course of a few months, who has raided on a fairly regular basis.  Because people work shifts, or just don't say much when we're raiding, or I just forget. 

I upload all that information - raids, boss kills, loot, attendance, through the Raid Tracker - and there is an option to pull a report of attendees for specific bosses .. but I just can't seem to get it to actually work.  It just brings up nothing. 

Ideally, rather than specific bosses anyway, I'd just like to pull a list of anyone who has attended one of our raids between two select points in time - say the last 6 months - and for it to show how many of the raids they've attended.  Is this possible?

As of now, I do not believe we provide that functionality. It's something we'll have to look at in the future.

Is there a guide somewhere for those of us who suffer from severe numpty-itis on what the various rapid raid reports, etc, do .. and how to set them?
