RE: Please test our new calendering solutions.
For testing purpose, I have tried out many solutions, but the two
most
suitable contenders are
1.Zikula
2.Citadel
I'm pleased that you're considering Zikula (I'm a member of the Zikula team
for those who don't know). I notice the lack of an SMS module concerns you - but this
should be simple to create depending on your required feature set. I'd be happy to
either do it myself or get a community member to look into as it would be of general use
to the Zikula community.
