To be honest, to me, it does not matter whether the design is from the owner or not, remarks on to whom the design belongs to aren't a bad thing at all. But shouldn't you FOCUS on something? Your forum's about everything! There are dozens of forums out there which are PRECISELY focused on each topic you try to put on one single forum. Ask yourself the question: Why should new users join you? (Give me a reason and I'll give it a try :)
