Currently I have around 4,950 followers on Twitter. To celebrate the milestone of 5,000 followers, I am going to give away a Domain Name to my 5,000th follower. If there is any doubt to who the 5,000 follower is, I will use the Twitter API to decide the actual winner.
I will use @NameCheap to register the name for the winner and push it to their NameCheap account.
If you do not have a NameCheap account you can set one up in about 2 minutes for free.
DISCLAIMER : I am in no way associated with NameCheap, I just love their system and it is what I recommend to anyone for Domain Name Registrations!
