Just a point I want to pick up on:
I know you people are very enthusiastic and dying to get on Google Plus, but would you allow at least 12 hours between requesting an invite via PM, before asking another (different) member to add you - I don't want to add someone who's already been added, which wastes an invitation!
Patience is a virtue - somehow, one of us will invite you, but please don't flood us with incessant and/or multiple requests - we're only human, and doing this as a kindness.
Thank you! 🙂
[EDITED]
See OP - you can now invite yourself!
