Am I, as a developer, required to link to BlogSkins and/or Blogger in my skin?
Per the Blogger Terms of Service, free Blogger users are required to link back to Blogger, so just to be safe, all skins must link back to Blogger using this button. Blogger Pro users can remove the picture if they wish. As for linking back to BlogSkins, it is certainly not required, but strongly encouraged :-). Future skin versions may require linkage to us, but we’re not sure yet.
