I have purchased several addons besides Credits Premium and while I have nothing against the copyright text, for my custom template it just looks bad and it stretches the space after the footer alot. If you look here http://www.tesoelite.com/forums/threads/the-best-class-in-eso-right-now.562/ and scroll the page until you get to the footer, you'll notice alot of grey area beyond that footer.
Hello, You can disappear copyright text by add following code to EXTRA.css template Code: #BRCopyright { display: none; }
