How could i make a theme for my admin cp?
Go into admin/styles/Axiom and download stylesheet.css and open it in a text editor.
It's just like editing CSS.
And the images in that folder are the cat bgs. You can re-color those in Adobe Photoshop or something of the sort.
After that create a new folder in admin/styles and upload the edited files there.
Be sure to name the folder exactly as you want the name of the theme to be. (eg. "My Theme")
oh and the last step
dont forget to release the theme, to the mybboard community
k, i'll try and if i like the theme(and even if i don't), i'll make it public
