I started the collection, Im aka MvH-.-
Was my original name. CC is my gfx partner. One other tut is by xclusive. The tut coming Friday will be by him, but yes all the tuts I have rights to as they are by my team members. The tutorials I made featuring other peoples sigs, I had permission to make as well.
We know most people fail at explaining anything in tuts so we try to fix that. We are as descriptive as possible and I hope that helps people, and like I said - New tut coming Friday.
