If you bulldoze a lot to build something new, you may find that when it is viewed in the Gallery, that it will claim the original was built by CSM_PersonalName (I'm guessing this is someone from EA).
This is easy to resolve though. When you first save a build to your library, it will tell you that the template already exists in your library. You will have the option to Overwrite, Save New or Cancel. If you choose overwrite, when you view it in the gallery, it will claim the original to be by CSM_PersonalName. If you choose Save New however, when vied in the Gallery, it will say that it is by you
