TinyPortal

I just started my site using Mambo with the SMF board and I'd like to run the board unwrapped but would like to add a Portal button so users could return to the Mambo part of the site, my problem is I don't know much about coding and I'm not sure how to do it.
I'm going to use both the Apollo & Helios boards although I can't seem to find the Red helios board, downloaded it from another section and I think I uploaded it right but it doesn't look like the red screenshot posted here.
Any advice would be greatly appreaciated.
BTW here's the start of my site, still lots of work to do.:)
