After months of struggling with this decision, we have decided to try a pay-for-download model for JCal Pro.
As many developers will attest, the donation model we have been using is simply not working. While a few generous folk have contributed (thanks to those BTW), there is essentialy no income from this project at the moment.
As a reminder to those not familiar with the GPL license of JCal Pro, it guarantees "free as in freedom", not "free as in beer". To satisfy the terms of the GPL, the JCal Pro source code can now be found at
http://joomlacode.org/gf/project/jcalpro/.
I hope JCal Pro users respect our decision, especially given the nominal fee of $5 USD we are charging.
