We now have a new private members category which can only be seen and used once you reach level 2 trust level.
You can use it for whatever you like, but my preference is that you keep most of the topics on the public forum so that all members can participate and can be seen by potential members who reach us through google.
The primary idea of the private section, IMO, is to have a place to air things you would rather not have broadcast on the internet. And I hope it wont become a place where we hang out most of the time and ignore the public forum.
Its better for the forum if activity, besides what we prefer to have private, is seen, IMO.
