I'm wondering if there is a plugin that would allow me to request user information such as email, name, address, interests, etc. I'd like to be able to create a database of people interested in receiving more info on a particular topic and be able to segment that list based on the topic. Does such a thing exist as a WP plugin?
Do I have to go with a third-party provider? for a fee? If so, recommendations?
Thanks for your help.
