Currently, there isn't, but we'd love your input on how to do this as we're investigating it. If we updated the users info from Facebook automatically, we think that would be problematic because some users would want different 'interests' or other information on a site-by-site basis. Do you have any suggestions on how best to do this without annoying some people who wouldn't want it to be automatic? Obviously, we could make it an option in the back end, "Always update profile information on login", or something like that.
Would that work? Are there any 'odd' cases-- you'd want field 'a' to update, but not field 'b', etc?
