I have a mailing list set up with a 3rd party email marketing company (Vertical Response) I have my WP site configured with a plugin that asks the user some additional info when they sign up (age, address, etc). What I need help with is this: when the user signs up successfully (i.e. the username and password they entered into Wordpress has been accepted and a new user has been created) I want the additional info they entered (age, addres, etc) to be sent via a HTTP post to another location (the mailing list I have set up with Vertical Response - data can be directly entered into their database via form submission (http post). Can anyone help? Please PM with any questions or prices/timescales to fix it thanks
