"It seems to be redundant having the notice at the top along with a tabber that links to the same thing"
Almost every page on this wiki with Book/TV-pages has the notice followed by the tab. This might seem redundant, but that's how it actually is. So if you don't intend to change it on hundreds of pages, better revert it back to how it was. ;)
The notices predate the tabbars, which were a later addition to many of pages. So the notices are kind of redundant now for the character pages. However the main admin of the wiki, AlbertEpstein, maybe kept it like this for a reason but he's been MIA for the past year.
