Go ahead and place logo change requests here in this same thread or over at the Graphics Request board. The .pbt file includes a blank logo and the header/base images in the images area.
I used two plugins to create the final look on this skin: Border Around Forum Using Images and Pebble's Head Base Side Images plugin both of which can be downloaded at IOD. If you can't access either of these plugins, send me a message and I'll send them to you. Enjoy!
