That sounds like a very different problem. The automatic welcome messages are one tool that helps alert users to their personal user pages and talk pages. And users that registered for the purpose of editing generally already know what they want to do next. I'd love to hear more about this narrative of users not knowing if they've registered. Have you talked to any of them?
