OF Collect User Account "Guest" or "View" for data viewing only

Dear all, when using OF Collect in multi-user environment, particularly (external) server, it would be handy to have a user account option "guest" or "view" for data viewing (sharing) only! After trying such user account by not clicking any of the roles (data entry, cleansing, analysis, administrator) first the message "Access denied" appeared but trying to login again with the standard "admin" account, the guest/view account activated as yet, exactly as I wanted: only "data management' could be accessed and data only viewed (not edited). However it does not work yet as it should do: 1) only after several login loops; maybe an option data view could be created, and 2) and when in data management window there is no "back to list" or "home" button; thus a useful issue for improvement. Suggestion: various viewing control options could be managed in this way?! Is this doable, other ideas, thanks, Joseph
