hello.. I plan to keep VB5 in a folder with the name "forum" vb, how to remove or setting "forum" next prefix in the web address

example address:
mydomain.com/forum/forum ------> due to be installed in the folder forum

the web address being:
mydomain.com/forum/

or explanation

I want to remove "forum2" when I entered "http://www.vbulletin.com/forum/forum2/",

because when I go to
vbulletin.com/forum/forum/vbulletin-announcements/vbulletin-announcements_aa

and I want to be
