I founded these group because I wanted to create a really elite group about web/logo design. The reason is simple, there are some groups which have great and good designers as members but also some designers who just started to do something with Photoshop. That's not bad but it ends every time with a submission spamming of non-quality designs.
Here everyone is allowed to join, but also this will be a group filled with high-quality designs. That means this group will not accept any submission which are under the average quality.
