Credits go to Rene Schmidt for two PHP classes used as a base to build the Captcha Library for barrier-free captchas.
The Authentication Library is based on Ion Auth for CodeIgniter by Ben Edmunds.
A hat tip goes to Andre Garcia, Trevor DeVore, Dave Cragg, Monte Goulding and Sarah Reichelt for their contributions as members of the use-livecode mailing list, and to Oliver Kenyon (RunRev).
The revIgniter framework is currently developed and maintained by Ralf Bitter (dimensionB Bitter u. Bitter GmbH).
