I put about 500 people into circles when I was trying to figure out G+.
You’re just going to let them email me on my personal, private, email account?
I know you need to get people using G+, but this is NOT a feature anyone wanted.
EDIT: I just emailed this to 500 of my G+ ‘friends’. If you received it, leave a comment, and let me know if this all-new spam functionality is working for you.
