It now seems you can sign up to Second Life with single name accounts. Before you could just signup to SL by entering your First SL Name and SL Second Name but now you are allowed one word Usernames. Check out what the SL Join page used to look like here. Linden Lab have recently launched Display Names in Viewer 2.3 allowing “greater self-expression for new users”.
- In Viewer 1.23.5 you will be known as Username Resident (example: Countdown Resident)
- In Viewer 2.3 you will be known as Username (example: Countdown)

I went ahead and created my new Username called Countdown to test it out.
