My site is 960px wide, and the buddybar looks great on the site (so far) as it sits centered right above the content. But, I’d rather have the buddybar span the entire width of the site (think 100% or min/max) while the rest of the site is still 960px wide. This will allow the bar to properly appear on the members blogs and the blog admin screens.
I’ve messed with Social Engine before…not a bad script at all.
Here’s what I’ve done with my BP home page for a site that worked better with a static 960px width layout. I know it’s not perfect, but please view with either Firefox, Chrome, or IE7 (I think 6 bugs out a little).
