This is a list of the first 500 ROBLOX users, ordered by ID. There are also join dates. If there isn't a join date for a certain account, then it is unknown, either due to the account being deleted or other circumstances. The reason why the join date for ROBLOX says 2007 is because ROBLOX's ID was switched in mid-2007, so this list keeps his original join date. This took me all day! So here is the list:
