Mod_rewrite - subdirectory - friendly Profile URL

We have our installation of IQ (4.1.0004) in a subfolder called 'community'

My mod rewrite for friendly profile URL is working if you put this:

http://www.myDomain.com/community/UserName

but not if you use this http://www.myDomain.com/UserName

. Can one of you fantastic people tell me how to get the friendly url to work given my subdirectory installation? It was working before we migrated but htaccess file did not make the migration.

Thanks  in advance

This is our current
