I created a question related to Gimp usage, because a few such questions were under the tag Gimp.

My question was closed.

I asked on askubuntu because I'm Ubuntu user. I know that Gimp is multi-platform and I could have asked on superuser (if they have different rules about particular applications). The other reason is that superuser don't accept my questions, though I don't have bad reputation there now.

Where should this question be migrated (webmasters, superuser, or another) and how to do it in my sitatuation?
