This could definitely be good information to have. I'm not sure if we'd want to actually have volunteers separately log their time; it seems like most of the benefits in terms of fundraising / appreciation of volunteers could be had by creating some reports based on RSVP / check-in data and the length of each event in Bridge Troll.
We would need to have separate tracking for things like organizing events or building Bridge Troll itself if we wanted a more complete view of volunteer time, but starting with just data on time spent by teachers/TAs seems like a good thing.
(Chrome dropped the final dash in the URL when I clicked the link, and it's necessary for the link to work. So in case anyone else has the same issue, just add it back in!)
