OH I just stumbled on this thread - and I do a little web work for April and her course
permaculture visions online PDC - we do have paypal, bank transfer and good old fashioned cheque! - we've spent the last year or so improving how we handle students and homework ect to help both students and teachers organize the course. We are big believers in open-source software and strive to keep the course accessible. Most of our course notes are original drawings and content produced in house.
We are always improving the course so your feedback is welcome - I'll see what we can do implementing a credit card function since the site is already on an SSL and safe it wont be too hard.
