Managing Scripto transcribers & Guest Users simultaneously


Does anyone have a solution that they like for managing both Scripto users (with MediaWiki accounts) and Guest users (adding items through the Contribution plugin) on the same site? For my current project we have both, and some people are getting confused (and I fear discouraged) by the two separate registration systems. I’ve thought about using Simple Contact Form as a way to artificially collect information from users, find out if they’re interested in one or both functions, and then add them to the appropriate registration system behind the scenes, but I’m curious to know if people have come up with other solutions.
