"I don't think the 'from' field makes an sense in the address sense (unless you are just geocoding to region or something)" - Sorry, I'm not sure what you mean

"I don't think the 'from' field makes an sense in the address sense (unless you are just geocoding to region or something)" - Sorry, I'm not sure what you mean by this. "Not sure what you are thinking of with respect to a use-case." - Bands and venues hopefully will create theses event or even use our pre-build calendar. (I plan to create more features on the calendar too.) Then the use-case would be the people who regularity visit band/venue sites. And that way even people with ride space will be reminded about carpooling. "If I were you I'd spend some time getting REAL events," - Totally. I have a few crawlers that get bands, venues, events. I just haven't put them on yet, because I don't know about legality issue. "Maybe even a screencast of who the actors are" - Will do.
