I notice some folks are worried whether or not this style will work with 4.1.5 ? Although I am not the designer I am a user and can report that I am running this style (both fixed and fluid) on my site and have had zero problems. I won't post my link on here as I always think folks are just trying to get traffic by doing such. But, I've been a vBulletin user for 4 years now. In those 4 years I have purchased approx. 8 styles. NONE of them were as clean and visually appealing as this one. FREE!!
I run 4.1.5
I love it so much that I am putting it on top of my list for support funding

Now as soon as I make any funds from my site, I'll get those checks in the mail
