no to charging i agree but there should be some application process so serious people come and get involved and the workshop is useful. I think some A4 sheet of quesitons or something to tax people a bit so you can weed out the layabouts. this should be publicised around the place, on bongo list etc, terra folk are great and their workshop will be legendary....
