how do i separate forum categories like vbulletin.org

[icemanic]

hi all, i remember this was possible but totally forgot how,

how do i get my categories in my forums to be split in two tabs/pages just like the vbulletin.org on top here, where there is a forums tab for the general forum threads, and then the mods tab for the forum categories pertaining to the mods,

how do i split up my forum that way, since i have so many forum categories the initital page is very very long to scroll down from

any assistance will be greatly appreciated.

thanks!
