Like others I assumed this was something like a VPN - so the term "network" needs some work.

Also the three icons and text for Post/Share/Chat look like they should be links - I spent a while clicking on them trying to find out what kind of features are supported, which was a bit annoying.

I did eventually find the sample network - no idea why that button is next to the register button it should be far more obvious!

Looks quite nice actually - I might use this to share stuff with immediate family members.....
