@Alejandro_Guerra, @Nexus, @Trelawny, we're happy to welcome you on-board.
@Alejandro and @Nexus, both of you have experience with Zentyal, and so are our other members here.
I think you'll have to ask those with previous experience. Check the link given by @alefattorini.
Hi @Nexus the more reason to spread NS and give a breathing room to clients.
That's good news!!! Glad they liked it as well as we all do.
NS started with small (but, mind you, capable) community. With it (and a corporate backing), NS has been a great product, how much more if the community grows? It will only get better. So we invite you to chime-in your ideas.
@Trelawny, there are also some community members here with ClearOS experience. I, myself, have tried and have put it in production...only to see it falter, not because of ClearOS itself but on the network card which is not supported. I really liked it better than Zentyal (at those times) but Ubuntu supports marvel-yukon which was erratic on RH installs (I think they say its all about something on how drivers are being detected and implemented...some years back).
