Hi mmullenders,
I can see that the board has already taken off. Great! Let me know the progress as I can't really follow it ;-)
Regarding the users, we do not have the location settings from each one, but we guess their location from their IP. Moreover, for some reason mailing lists are not the communication channel that is working the best for Zentyal users, so my advice would be to avoid it.
I am not very keen on spamming forum users with lots of announcements, but maybe we can send a short email to Dutch-based-IP users with a short notice saying something like "Hey, there's now a Dutch-based board in the forum. You can check it here. Sorry if this email is not of your interest". What do you think?
Cheers,
