Changing the main "orange bar" to a different colo
 

How and where? I apologize to ask so many questions, but some of this stuff I just cannot find.

take a look in the skin1/images folder

youll find all those bits and bobs in there.

The easiest way is to just load the images there into you graphics package, change them , save them and upload them

Thank you. :D

Also, the template where that image is displayed is:

/dialog.tpl
