user profile text fields

regarding user profile text fields: name - should be 2 fields: givename,surname (its good to split these up for sorting) email - definitely needs to be in its own field as its their login title - i would drop: leave this up to them to put in their bio if they choose postal address - i could see city/town & country might be useful, might be too invasive to ask for complete address hyper links - if we want multiple it would be good to have a set limit to keep the data model from getting more complicated
