Hi, after reading all these replies and the whole discussion, I think I'll revisit my points this weekend, reading all the OGo docs again, but I beg you guys to do the same with Kolab. Kolab 2 is being designed atm., and it would be nice to have a 2nd solution next to OGo. Suppose you are right, and OGo is atm. the best solution, then it will still benefit us to have more then one option... Maarten
