Am I allowed to pay money to get a shirt that I design that has the SCP logo on it, as long as I don't make money off of it? Again, I won't earn money off of it. And it will not feature any SCP description, picture, or otherwise, nor any slander toward any user on this site. I would ask this on the chat, but for some reason I can't get it to work.
Long story short, nobody's going to stop you from doing whatever you want with SCP material as long as you adhere to the terms of the Creative Commons license.
Keep in mind that this means your derivative work must be CC-licensed as well.
Ok. But does anyone know who created the SCP logo? If so, then I would like to ask the author if I may use the logo. I would of course attribute that logo to him/her in the fine print below, as well as have the link to the SCP wiki. I also plan to have the link to the new website on it too, so it won't get outdated. Anyone who can point me out to the author so I can PM him/her would be a great help!
