I don't want to change the way registrations are done. It makes sense to require a username, password, email address for forum posters. What I would like to do is allow people to subscribe to the SMF newsletter with just an email address. This would basically create a ghost account in SMF. If they ever wanted to create a password for it, they could do so somehow and convert to a full forum account. Otherwise, they would only be on the recipient list for periodic newsletters.
Please let me know if I'm missing a mod or something somewhere that does this. This is important for email marketing that I would like to be uniform to members and non-members alike.
Thanks!
