Hi Trevor!
No one seems to be around, eh?
For tech questions/problems such as font size or reasons why you can't get a listing to post, I would file a support requesr directly with Auctiva. They WILL give you help.
As for the FB, mine too is exactly the same as the day I signed up but I guess there's really no need to change it. Your FB on Ebay should be increasing as it normally would, and that's the one folks will see.
