OG "Add people" username predictive searching In OG7, I have given one user the role of overseer and that role has the Administer Organic groups permissions enabled so he can administer all Organic Groups on the site.

So, for each group, when my overseer goes to Group -> Add People and he attempts to input the user name, the textfield does not predict/provide suggestions of matching user names. However, this helpful effect does happen for the site administrator.

Can anyone tell me how I can enable this user name prediction effect for my overseer role?
The permission to set is "View user profiles".
