To select from the available (new) skins, select the ‘user CP’ tab (up there, on the left…)
From there, on the left side, you’ll see a menu with “Your Control Panel” at the top. Partway down, is “Settings and Options.” Within that, select “Edit Options.”
Scroll down towards the bottom, and “Miscellaneous Options”. One of them is “Forum Skin”. There are several different choices there. Select one, then at the bottom of the page, choose “Save Changes”. It will immediately be implemented and you can see how you like it. Repeat as necessary until you get one that you like.
Personally, and I’m sad to say, I don’t really like any of the current choices, preferring the old Gulf skin (although I find the Gulf color scheme to be very trite and overdone, the forum skin was more favorable to me than any of the other alternatives on offer at the time). The least objectionable of the new skins, to me, is “Mk II Le Mans (Light)”
But of course, each of us will have his own opinion on his favorite…what I'd like to see is one that reflects the 1965 Shelby colors of Guardsman Blue with white stripes...but this is a trivial matter in the grand scheme of things. I'm just glad this forum exists and that people like Ron are willing to devote the not-inconsiderable amount of effort to keep it going!
