Many of my forum's users are reluctant to sign up as members. I would like to allow them to ask a question as a guest. However, I'd like the board to interact with this guest (who started a new thread) in a similar way the board interacts with a member, primarily: - Make it required for a guest to provide an e-mail address when they start a new thread - Have the guest receive an e-mail notification each time a reply has been posted to the thread they have initially created. I'm looking for an add-on to accomplish this, or for a developer to create one. Any help appreciated!
