Came across this excellent jQuery plugin, which links into your signup forms and prompts users who mistakenly enter their email address if the mistake is a common one. For example, if they type foo@gmail.con instead of it doesn’t prevent it submitting, but prompts them “Did you mean Works for hotnail and so on too. Very nice; apparently they measured how effective it was and it did reduce bounced signup emails by a measurable %.
