This is a forum to suggest new features for mojoPortal.
"Add existing user to role" shows a popup with a paged list of all users, using /Dialog/RoleUserSelectDialog.aspx?r=N
In the Store, against the details of each order, we have "Lookup user" which shows a very similar popup, but with a Search box - very useful! This uses /Dialog/UserSelectorDialog.aspx
It would be great if this search facility was available on the Role version as well.
