htaccess for root for other directories

I have an htaccess in /forums, but would also like to have it in root so I can use for /photopost/

What htaccess do I use.

I have written down the following, but not working properly.

Code:

RewriteCond %{REQUEST_FILENAME} !forums/
RewriteCond %{QUERY_STRING} !vbseourl=
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ forums/vbseo.php?vbseourl=$1&vbseorelpath=../&%{QUERY_STRING} [L]

It seems to be correct (you also need "RewrwiteEngine on" line though), what exactly doesn't work in this case?

I also have similar problem here.
VBSEO on the same level as forums directory
