To handle user urls for login and logout i hacked every mention of "/users.php?mode=modetype"
into
/useradmin/modetype/

Then created a new folder called useradmin and then created a .htaccess document in this new folder. the Mod_Rewrite rules in this doc are:

RewriteBase /useradmin/ RewriteEngine on RewriteRule ^(.*)/$ /users.php?mode=$1 [NC,L]
