You could create a group "all" which is private - hidden - no tags.
Every user is member of this group. So you cloud mention the group @all where all users are members.
How to allow search users for guest? Guests redirects to the login page.
Go to ACP -> Settings -> General and select "Allow guests to search without logging in"
I realize this is probably not a great place for it, I'll move it to the Guest Settings page soon.
Yes, I was referring to search users.
Perhaps can replace a piece of code to allow guests to search?
i cant find this menu anymore?
