if you heard you could do this with a .htaccess or httpd.conf, then they were probably referring to
mod rewrite.
basically you would use regular expressions to change business.crossmediagroup.net/forums to forums.crossmediagroup.net. i think you would accomplish the same thing by creating a symbolic link between the 2 forum directories server-side though.
Are you sure there is no "forum path" setting in the invisionboard control panel? there might be something in the scripts that is causing the error based on the path it's hosted at.
thanks for understanding and fixing the sig. you are 100% right, but you'de be suprised how many people have register and post just for the purpose of SEO. we work hard to keep the integrity of the information here. it just comes at a small price for new members.
