Anyway yeah, I did manage to log on within the first 30 seconds of launch (literally) and grabbed whichever names I was after. Shame only 5 characters are allowed, but you won't believe how fast the 3-letter names went within the first MINUTE of launch. I got Yay, didn't really try Joy. Not really gonna complain since I got the ones I was after, I'm sure there were people with a whole list of names they started spamming at launch.
Urgh, reminds me of getting an original name in Runescape back in 2006. Reached a stage where having a short/original name went hand-in-hand with having a super high-level with countless hours gameplay time, people would literally worship you with "whooaaaa the original?!" and seeing "nn" (nice name) all the time actually became a thing. *shudder*
Also I'm a guy
Safest to assume everyone on the internet is a guy at first (unless they give overwhelming clues of being female :P) and wait for them to correct you if they're not hehe.
