Redirect Error vbulletin 4.2

[airbrushtutor]

Hi guys and girls,

Another redirect error slight issue i have after loading the latest 4.2 -

if i type in the home URL 'www.airbrushforum.org' it redirects me to 'www.airbrushforum.org/forum' - this makes sense, however i have 'www.airbrushforum.org' set as the home URL - i noticed the page rank has been passed over aswell, but i'm just wondering if this is a redirect due to the new tabs manager and if this is a setting that can be changed?
i haven't found a solution so far..
thanks!

Just wanting to find out if this is something to do with the new navigation tabs manager and if there's a way i can get the home page URL to be airbrushforum.org instead of airbrushforum.org/forum? cheers
