Google+ Invites got modified slightly to let users invite anyone with a reusable URL that you can use to share Group of people to your Google+ Circles. There is also a limit of 150 invites per user which shows google+ team is trying to limit the total number of users flow. However, we believe the invite system may get automatically increased when we used all the invites.
- You may invite upto 150 Users only.
- Unique Reusable URL Enabled
Ofcourse, in other side when we think about google+ account removal and other activities, it may left you with Zero Invites. Chances are there for any thing to happen.
As we have 150 invites left, you can request one here as a comment below. You can add me in your Google+ Circle once your gmail account got Google+ enabled. Happy Social Networking.
