User:Admin

The first person on roblox was of the name of 'Admin'. His/her original ID was 1, but later moved to 18, as shown here: http://web.roblox.com/My/NewMessage.aspx?RecipientID=18. You need an account to view it, but the 18 on the link shows his/her ID. No one is sure why his ID was moved, and why he was banned, but it was probably for testing purposes.
