Changed: in the Magpie app, joining a team with the link in an invitation sent to your email address waits until the address is confirmed. Until then the invitation says Confirm your email address to answer invitations sent to it, with Send a new link. On the website the link works as before, and answering with it confirms the address.
Fixed: when the account at an email address had not confirmed it and was on the team, the team's admins could not invite that address. They now can.
Fixed: a guest of a team did not see a second invitation to that team on Your teams, such as one sent to their email address once it was confirmed. It is now listed, and accepting it adds what it gives.
Fixed: resending an invitation by handle emailed the address the account had when the invitation was first sent. It now goes to the account's current address.
