Hi
I have rigged up a Portal/Forum theme display server. So far I have managed to get Joomla, Xoops and SMF to work in the way I want. That is to display below a menu. Quite tricky to be honest but it seems to be working well now. Also I have built into the menu direct links to the theme zip files. You can also jump between Portals and Forum demos using the left side drop down menu. As long as the server is up the themes should change rapidly, and there is an online indicator on my site's first page. Other demos will follow. Only 10 SMF themes on at the mo but then I only managed to get it working today so expect a great many more shortly :).
Regards
