i have included a simple iframe file that will add your forum or any other link into the kb structure

to use open file and change http://localhost/forum/ to your forum url or the url your wanting

save and upload to your /common/ dir

access same as any other file in kb /index.php?a=forum

you can add multiple iframes pages by saving the file as another name. eg. mining.php

then access by kb /index.php?a=mining
