Hi,
– when someone registers an account, it is automatically in “not yet approved” status. During this time, no-one can contact them with a PM or a friend request. They are however contacted by the Welcome Team, and depending on how quickly they respond to this their account goes into “approved” status. So the time delay is down to them, not to the site admin. If they simply do not respond, then after a few days the account gets deleted.
– once newly “approved” there is a period of three days where only Verified Members can contact them with a PM/Friend Request. The new member however is free to contact anyone. This puts the control & choice in their hands, and is intended to lessen the issue where new female members get an avalanche of annoying messages immediately after approval.
– three days after approval, anyone can contact them.
I hope that answers your questions.
Thankyou.
