Forum default is a lot less "offset spacy" and is good enough to fix the current fiddle issues without having to go all the way back to Old YaBB 2.1 (in saying this I also use Adblock on both my browsers, so the add bars show up as empty spaces when they show up at all, but Forum Default and Old YaBB 2.1 will definitely fix the current fiddle issue for you -- until the roving fingers fiddle again, that is.
Be aware that Old YaBB has old menu names for the various functions (so don't get yerself all bumfuzzled & lost in the old nomenclature).
How do I do this ???? CPanel in the login/logout bar
Profile (kinda stuck in the blue bar right under SuzukiSavage.com)
Options
<log in with your password>
go down to second from the bottom "Which Template do you want to use?"
pick one then hit "Change Profile" at the very bottom
We all use different browsers and different OS systems, so what works good for me might not do the same for you .....
...... but tuning how the site looks is something YOU CAN DO VERY EASILY.
