Nice theme! Have a question about advertisement sizes. I know they are set at 125 x 125 by default, is there any way to set the default to a larger size (i.e. 250 x 250)? Which brings up my other question, I'm using the "One Big Sidebar" option, what is the largest width for that option? We want to give advertisers viable space, and the 125 x 125 is too small.
Appreciate the help.
