Describe the goal you'd like to achieve

As a pollowner, I want to be able to select contacts when sharing polls, because it helps to find them if you mixed up contacts and users.

Describe possible solutions

It would be great if the poll sharing mechanism checks if the email of a contact is also a user and then puts in the right userid.

Additional context

If u select the persons from contacts the dont see the poll as relevant. If you dont have contacts for them its hard to send them mails.

I don't get it.

If I add a share by email address, I find contacts and users as well.

But if you have contacts for users (maybe thats the fault in our config) and someone selects the contact and not the user (by name not by mail) then the mail of the contact is put into poll shares userid and email. Its not very important but maybe its easy to check if the same mail of the contact is also used for a user and then put the userid into the db field so that the poll is showed as relevant.

[dartcafe]

If you add a share by name or email address for a person you get a selection for both hits; The user and the contact. It is up to the user, which he chooses.

Search by name	search by email address

How should the app tell if the user chooses the contact by intention or accidentally?
