I'm able to sign up but my activation e-mail never arrives (maybe because of some fw? I can see the e-mail text in the terminal, though.)
When I'm not activated, I can't use the "Forgotten password" functionality since that only works on active accounts, it seems. This means that if someone manages to lose their activation e-mail, they have to choose a new account name.
As a fix, I propose simply treating the "Forgotten password" request as a "Activate account" request.
Clarification:
As a fix, I propose simply treating the "Forgotten password" request as a "Activate account" request only when the account has not yet been activated.
As raised by @jarlarntzen on this PR.
Must investigate.
