I'm cleaning-up my database, and for the sake of keeping SPAM down to a minimum I would like lock all of the wordpress user accounts that do not contain an e-mail address. Any ideas how to do this?
Please keep in mind that my level of PHP experience is "code tweaker" - most of the time I don't know what I'm doing but I'm able to personalize someone else's solution to my needs. My level of MYSQL is also pretty low - I can get around in there but I don't know how to make declarations that make things happen.
