Google+ question

I haven't had much chance to play with my Google+ account, so maybe someone can answer this for me. I understand one can make new circles and name them what they wish.

1) Can a contact be a member of more than one circle?

2) Does a contact see what circles of yours they are on?


(i.e. If I make a circle of Acquaintances called "Marks", can they still be in the Acquaintances circle, and do they see themselves listed as both Acquaintances and Marks?)

The Problem with Musical Coworkers...

is that while they are fine musicians they are overcome with weird compulsions to send you things like this, because it is stuck in their head.
