Whatever you decide to do, stay away from craigslist.
If Craigslist is full of flakes, where would you suggest I start networking?
Thanks Ltressel, but I actually am not developing any proprietary VoIP software. The development I`m talking about is simply the web interface and database that allows students to be matched with tutors via their schedules and social criteria. After that, the tutors and students converse through Skype or actually any other VoIP medium of their choosing. It`s all one-on-one, and students and tutors incorporate or don`t incorporate study materials as they see fit. It`s quite decentralized and peer-to-peer. It`s not my intention to compete in the web-classroom market; with some 9 million subscribing customers, Englishtown.com has that just about pinned down.
