When making glitter texts, the addition of credit is up to you.
When I make snags, I always put my watermark on them somewhere on the snag.
I remember a PSP group that I was a member of would put their group name on their snags like the one below.
I don't care about advertising any of my groups, but it would be fine with me if you wanted to do something similar using any of your groups. The choice is yours
