Ok. I installed the mod, and it's pretty freakin' awesome, thanks!
*But* I don't think it solves my initial dilemma.
On the Gallery homepage, the main menu in the header, is highlighting the Forum menu item. This is because the Gallery is using the forum header (and the Forum menu item has a class of "current" make set the green box to it).
I tried disabling the use of the forum header and footer, and using a Gallery header, headtags, footer but I lose the Forum login box (at the top of the page).
So, I tried simply copying the code from the forum header, headerinclude and footer templates into the Gallery header, headtags and footer templates, and that doesn't work (all the
vb: code is displayed).
I even tried making duplicate header and footer templates in vBulletin and change the Gallery code to use those (not sure I was doing it exactly right) and no luck.
So I guess I am trying to see if y'all have any other suggestions for me to try?
