Monitoring the blogosphere on Naymz shows that people are fed up with the reminders that they receive to apply for the service. I read in the FAQ’s that the person that invites can remove the list of invitees. When you do that right after the first invite your friends won’t be bothered with what they obviously consider spam. If everyone that invited someone else removes the invitees in their account and do this by expiring the pending invitation before the mentioned date of expiration this would make a hell of a difference. So it is also the invitees choice to allow Naymz to send reminders. I assume that few who invite are aware of this.
