mod_rewrite friendly URL's for social groups?
 

Is there anyway to setup search friendly URL's for social groups? I've got mod_rewrite friendly URL's turned on in vbulletin options. It seems like the URL's are being redirected correctly using my, however I need to change all the URL's to the individual groups to match the new URL format. Is there an easy way to do that?

This is my rule:

RewriteRule ^groups/([\w]+) group.php?groupid=$1&%{QUERY_STRING}

The group links on www.mysite.com/group.php all still point to:
www.mysite.com/group.php?groupid=2 instead of www.mysite.com/groups/2-Group-Name. However, www.mysite.com/groups/2-Group-Name is accessible.
