Topic: user identification

this is problematic mostly for portal admins but may also be an issue for everybody else:

when e.g. assigning a reviewer, all one has at this stage of selection is their name. now sometimes there are multiple accounts by the same user, sometimes two users have the same name. every time a user name can be selected at least on admin level if not in general one should have the possibility to check that it's the right person by seeing additional information (popover?) such as tagline, affiliation, abstract or photo. If there is an ORCID Id, maybe pull data directly from there?
