Guest means that the member resigned their membership. I always find it sad when that happens. It is like a death in the family.
I never really understood that. Why not just not log onto CC? Instead of cancelling altogether. That's what I do, anyway, when I don't want to deal with people.
I don't understand this either. It is best to just not log in rather that deleting your account. Even if you create a new account there will be many members that don't know who you are. You also lose all of your likes and rep points and green bars.
