Is there an addon or method whereby a Custom User Field for all members could be visible to members of a premium group? For instance, I'm building a forum for a small organization, for paying members we want their First and Last name to be visible in the threads to those that are premium members, but we don't want guests (and search bots) to be able to see their First and Last name. Obviously, we prefer that the username not be their first and last name. Thoughts? Maybe as a signature that is only visible to premium members?
