Credits
revIgniter is modeled on CodeIgniter. So, first of all credits go to Rick Ellis (CEO of Ellislab, Inc.).
Credits go to Rene Schmidt for two PHP classes used as a base to build the Captcha Library for barrier-free captchas.
A hat tip goes to Trevor DeVore, Sarah Reichelt, Oliver Kenyon, Andre Garcia and Dave Cragg for their contributions as members of the use-revolution mailing list.
The revIgniter framework is currently developed and maintained by Ralf Bitter (dimensionB Bitter u. Bitter GmbH, softwaregestaltung.de).
