Embeding forum in to css frameset (Design/Themes)
Yes you are quite right, I am sorry. Poor choice of language. I also forgot what time of year it is! Oops.
I figured the css frame stuff out anyway. It is indeed just a case of modifying main.tpl with your layout object tags and you can just append any custom css for the wrapper etc to the style.min.css file as I suspected.
example: http://grognard.net/forum/index.php?mode=index
Hopefully this will be useful to other newbs like myself wondering how to embed my little forum in a frameset.
