|Summary||0008685: New users aren't warned that another user account has identical e-mail address.|
In large corporate environments, users sometimes register once, then forget they have done so and later register another account with the same e-mail address. This leads to duplicate, unwanted accounts on the system.
I recommend that Mantis should warn users when they try to register another account with the same e-mail address, or, at the administrator's option, refuse to register such a duplicate account at all.

I removed the following from your description, since it should be a reported as a separate bug:
"Note that Mantis does refuse to allow two users to specify the same "Real Name" (Application Error #807). However, by this point, the duplicate accounts have already been created."
Ideally I would like to see the banning of multiple accounts with the same email. However, we will have to take into considerations upgrades from previous versions which allowed that. Following are some options to help solve this issue:
However, blocking creation of such accounts with duplicate emails is an easy step that makes a lot of sense. I just don't think that we need an option to allow it.
Yes, I'd favour a complete ban on registering duplicate accounts with the same e-mail address. That's one use for the "I've forgotten my password" option.
However, ensuring a consistent upgrade path for current users is important. My view is that anything already in the database can stay, and the ban only applies to new logins being registered. This means that existing users are not disrupted.
In terms of your suggestions:
In terms of a page showing the number of logins, actions etc, this would be useful as a generic page, and simple to generate. I'm trying not to go off-topic, as this would be valuable as yet another feature request :-)
