UBB.Developers Forums Community Development Programming PHP and Server-side Scripting SSI Question

I'm a bit new at working with SSI and Perl just so you know.

My question concerns both UBB5.XX and UBB6.

I want to set a DHTML menu as the header for my forums (pretty much the same idea as what is being used here at UbbDev). How and where do I include the SSI onload tag so that it loads with each forum page? I realize it may not be so easy with version 6 since it has no HTML pages with a BODY for the tag to be included in, but since I will be upgrading I need to know how to do it with both versions.

Any help or instructions you might be able to provide would be greatly appreciated.

You'll probably get more answers in the UBB forums, this is primarily for non-UBB related scripting.
