If I invite a user to join my Displayr account, they must click the link in the invite email before they can join my account. If an invited user has an existing Displayr account, they can log into Displayr without accepting the invite but get a message they don't have access to my account, even though they can log in. Or, if they're a new user, they get an error saying they don't exist. The change here is that Displayr would force a user whose account has outstanding invites to accept them when logging in, rather than the link in the email being the only way to accept invitations. Similarly, if they're a brand-new user and have an outstanding invite, if they attempt to log in directly rather than using the invite link, Displayr still takes them through the signup and password creation process. This is not a huge pain currently but it would smooth the process of inviting users and reduce confusion where a user thinks they don't need to accept the invitation because they already have a Displayr account elsewhere and worry it could be a duplicate sign-up.
