I'll try a more full explanation, that first one was a bit sparse
I have a blog setup in the directory /pmachine where a 3 col blog layout is controlled by css.
I'd like to wrap a php/MySQL discussion forum that is installed in /pmachine/forum/ into the blog by somehow having /pmachine/forum/index.php called into the content column div of the blog page at /pmachine/weblog.php
include('forum/index.php') in the content div didn't work as the forum script couldn't locate other component information that it was looking for that lives in (for example) /pmachine/forum/include.
Somewhere as part of the include I assume I need to set additional information to allow everything in /forum (and below) to be found so that it all works properly.
Thanks
