Donations Always Welcome!
I wrote iGroupCal for myself. As a thanks to the guys at OpusFlow who offered some developer support I agreed to publish my work for free. Of course, I do hope that I can help the Mac-heads in a hostile Windows environment in some small way too!
As you can see, I've put some Google ads on these pages (relatively unobtrusively, I hope) to help defray some of the cost of developing iGroupCal. Why not click on one, just for fun!
If you'd like some technical support for iGroupCal in a commercial setting, or would like to encourage me to continue with my development of this project, a small donation would help to make your case.
