[ckan-dev] Forgotten usernames

[Ross Jones]

As Toby pointed out, it's called sub-addressing and + signs are definitely valid parts of an email address (as indeed are ( and ) ).

I wasn't necessarily suggesting behaviour that would resolve the forgotten passwords, rather behaviour that would allow us to implement 'login via email address'. I don't like the idea that I can put in an email address and get a username back, others may disagree, but I think several usernames with one email address makes email address login a 'rough edge'.

They should still get delivered as they are valid email addresses.   Not sure how straightforward that would be to do in a sql migration though.
