Changing the font to 13pt site-wide '''without permission''' violates the TOU. :edit: No, it won't. [http://community.wikia.com/wiki/User_blog_comment:BertH/Fluid_layout_has_arrived/@comment-EternalBeast-20131205075932/@comment-BertH-20131205231649?permalink=605815#comm-605815 See BertH's comment here] If Wikia Staff give you permission to do something which would otherwise violate the TOU, it's not a TOU violation. If you have a good reason to need the font-size to be 13px, tell Wikia Staff via [[Special:Contact]], and link them to specific examples of pages which need to be 13px, and maybe they'll see things your way.
