I'd like to add a property to the user profile (mysites) that allows the user to pick multiple users from the people picker control. It looks like the Person control only accepts 1 value by default. How would I go about allowing multiple values?
I don't where is the people picker that you are referring to? First thought My sites Colleagues but double checked and accept multiple users Anyway the People Picker support multiple users and you can change this from the column settings.
Hope this helps if not can you provide more info about where exactly is that people picker?
