Having two accounts, with the same email address

[magitam]

When a second email address is added to a profile, if that email address is already in the system, it should merge the profile details together, rather than retain two individual profiles. At present, If you add a second email address to a profile that's already in the system, the second email address is just added to the profile, with no prompt from the system to 'merge' your existing profile, or cliques.
Maybe linked to Issue #7, of not being able to verify a second email address
