I have a few ideas about making it easier for Commons admins to discuss with people: A) With SUL, it's probably easy enough to make sure that at least the "homewiki" of a user is prominently shown on their Commons user page. This would allow for: *Better communication (you'd know what language those people speak) *Better and more to the point warnings (you'd know if someone is a newbie or a long time contributor) B) Could the Commons talk page be embedded in the homewiki talk page somehow, allowing for people to get their message where they are at. Or at lest have a warning "your talk page on commons has a message!" C) If SUL does not allow link to homewiki, or if someone creates an account directly on Commons, maybe in the login page, they could be asked to link to their homewiki account. These are just ramblings. Commons is my project of choice, because I think it is one with the biggest potential, so I'm biased :)
