Double confirmation of e-mail address?

[mowlman]

Email is very imporant to us, we send our invoices and shipping notifications and use it as a main account identifier.
I would like to make the user enter their email twice, thus  drastically reducing  the chance that an e-mail address contains typos.

What would be the best method? ...Create a new VM user field , then create some javascript to make sure email1 is the same as email2?

VM: 2.0.20b

Bumping , Anyone want to comment?    I was thinking of creating a new VM field "confirm email", then copy code that is checking password and confirm password to use for email? Anyone else done this, any pitfalls or gotchas? Thanks.
