EDGY - July 7 - LinkedIn has introduced page invitation credits, alongside other measures, to prevent users from spamming page follow invites. The new page invitation credits can limit the number of invites that LinkedIn page admins can send out each month. Before now, page admins could send as much as 50 invites per day. That's a 1,500 invites every month. Page admins will now have access to 100 credits per month for inviting connections to follow their page.
