I don't know how to put a watermark on my stuff. Every time I've tried to, you have you sign up and pay for copyright watermarks. Unless you do it with GIMP then it leaves who the image is made by if you fill out the box that says "Created with GIMP" and change what it says. I haven't found any other way to do that.

I just design siggies based on what the images look like. Pixels stay with pixel fonts.
And everything else is random based on their design but I don't do it intentionally, it just happens. xD

But I've noticed you doing that. I figured you'd follow some kind of organizing way to do those things.
