UCreative is a social network for creatives of every type available.
I first found this network in a post on Workawesome, and proceeded to checking it out.
As far as I can tell it is free to join, but it requires a waiting period for approval to the network. You can chat with other creatives post your work and ask for help and opinions. I’ve already signed up but am still not quite sure what to think of it, it sounds like a very interesting and useful concept, but like many other networks it will depend a lot on the way that people use it.
