For some reason I can do just fine with others and finishing their styles but I'm so darn OCD I can't square mine away LOL!
Here's a paid style I own for 3.x series, the developer has not updated to 4.x yet however I asked and they gave me permission to update and use in a subdomain on my site so this is a clone of my 3.x style in 4.0 format with custom css including the navbar and custom wrapper codes for anything else I want to add in

. I also utilized the old tabs as I wanted to keep them instead of removing them. I did replace the standard navbar sublinks making them links to the forums instead and the tabs have new css as well for a custom drop down menu by Dynamic Drive that works well in all browsers with a slight fade effect.
I might change it to the two column design, check that out by Lynne here:

Quote the post if you like it otherwise go easy on me as it did take a bit of finesse to convert the style so at least give me credit there rofl
