Just remove eddiedowns form users table in database,
@DEEPAN - this is a 2 year old thread, I'm sure it's been resolved, but deleteing a row from the users table is a terrible idea. For future people, do not do that.
You should not edit Db directly. See http://docs.elgg.org/wiki/Should_I_edit_the_database_manually%3F
Theres a plugin called welcomer that might do the trick

Actually, playing around with the language files does the job.
Change the validation mail and add your content to it.
Besides, this plugin takes a member to a page after the first login, doesn't really send a welcome to message to his/her inbox.
