The domain will remain in "Pending Delete" status for 5 days.
After this it will be deleted and available for anyone to register.
Warnings:
It drops exactly 5 days after it first moved to "Pending Delete" status.
So if that happened at 2:00am, then it will be deleted at the same time.
If it is a "good" domain name then bet your life others are watching it to - including those using "snapping tool" and "snapping services".
They will beat you every time to registering the domain once it drops.
If it's an obscure domain name then let it drop and try to register it.
If it's even slightly good, then you'll probably have to use a back-order service who will stand a better job of snapping it up for you.
