[split] Merging Kunena -> SMF -> MyBB 1.8
well, if you are interested in MyBB then you can keep only MyBB system files.
if you also like to keep the other systems (for reference as archives) then you can keep them (in different folders)
if you move MyBB system files from sub-folder to main folder then you have to also change the forum url
and related cookie settings first in ~/inc/settings.php file and later at the settings of admin panel.
more details on cookie settings
note: ~/inc/config.php file contains MyBB database details
