Hi Manu. Thanks for the reply. I'm afraid that doesn't help because i wouldn't know the title of any of the user's items and some haven't created any items at all.
The need to search for users across the AGOL community is because i work across many different portals with many users who are either employees or contractors to the organisations and its a nightmare trying to keep track of it all, especially when contractors have been signed up just so they can use Collector in the field and some don't even know what organisational account they are a part of.
It would be great to have one place to search for everyone who has listed their user as publicly visible.
