To tell you the truth, I didn't think of this as spam. Although now that you mention it, I can see how one might. Others have posted skins that they are selling on Aximsite. I didn't think I was doing anything different or wrong. I hope I haven't offened anyone.
There were some heavy weights who said stuff before I did, but I would like to add that it is a bit frustrating to be looking through the forums for some stuff to try out (free) while learning various things and to find out that the items are only for sale.
I do think it would be great though if you worked with Chris and did advertising on the site (or whatever options he has).
