have you used "Site Organizer" from Kaktusan Corp?

[oast]

I've contacted Kaktus a few times about the script... he works hard but I feel he's given up on SO in favour of his other scripts.
I wanted it to be XHTML compliant and also have the option of naming my own styles... I might end up doing my own templating system in the near future, but hey, it's free, so I'll put up with it for now...

Have a look at http://tgp.fthq.com/ and http://tgp.ukmast.com/

They are two of my SO TGPs...
Each layout is essentially the same, running from the same template.
I use a lot of PHP inserts... even the CSS is a php file to change the site colors depending on the domain... and mod_rewrite (to appeal more to the SEs), but if you want; PM me your address and I'll send you one of my first templates, so you can see how I use it.
