Well if I put it in the FREE FREE FREE thread I'd get people taking me up on it just 'cause it's free! I'm more than willing to give up the dollar worth of film and the bulk loading cartridges and the couple of bucks in postage to folks that are seriously interested in trying this out, but I'm not looking to send film into everyone's "that might be neat someday" junk drawer.
You're right, and I"m not suggesting that you whore away your efforts, which by the way are incredibly appreciated. You could introduce a caveat in the post about processing and your expectations. It'd take a little faith in your fellow APUGger, but it could work.
In reality though, I think you should just charge a bit for it. I'd be totally fine paying $5 for a roll, shipping included or something around there.
