That's what I was thinking of doing at first.  Perhaps I'll run the charity annually and just not expect too much until I build community trust.  The next big drive is a few months out, so I have some time to work out the details.

I'm going to contact the SD CCFA and see if they will accept donations in BTC first.  I think that would be ideal.  That way the organization could convert the BTC to USD if they wish, or just use BTC to fund programs/research on their own.

I appreciate the suggestions    I'm afraid I have more enthusiasm than knowledge, so your insight is very appreciated.
