Several times I've tried to find out what pronoun to use for someone with an ambiguous name, by looking through their comment history, and failed to find that information. It would be nice to have a quick way to get to someone's post on the Welcome thread, as a sort of profile, or at least regular account profiles that contain this information.

As it is, using "they" to refer to a specific person, guessing incorrectly, and posting a comment to ask which pronoun to use are all socially discouraged. Using names every time works, but is sometimes awkward.
