CreativeGates and WorldGuard permissions problem HELP PLEASE!

Hi, I have downloaded Creative Gates plugin and World Guard plugin (with world edit), for ops (admins), all work great. But I login with new user and when I go to a gate created with CreativeGates it says: You don´t have permission to use a gate (or this gate or something like that)
I think I need some permission plugin but what plugin and how can I configure it.

THANKS

I think the simplest and best Plugin for Permission in the moment is PermissionsEx watch a tutorial on youtube and create different ranks with the permissions. The Permissions for the Plugin you can find on the bukkit site of every Plugin.

sry for my bad englisch

Done. Thanks!
