Will you please list 3 members, one you like, one you dislike, and one you feel indifferent about? Others may guess who is which, but you may choose to withhold that information.
Post three usernames so other people can reply with three descriptions, opinions, messages, etc... but in any order and not indicating which refers to which person.
Will you please name 5 members and say something to/about each of the members? The twist is that you have to list the names and messages separately and in no particular order so they don't know which message is about which person.
