Here you go: http://www.twitch.tv/superwandermark all the videos are there. They were live streamed, you you'll have to skip around a bit to find the good bits, but they're worth watching. ;)
Regarding name colour, the colour of your name tells others whether you have bought the game (yellow), are a in-game 'guard' or 'global moderator' (green), are a forum admin (red), a developer (purple), or none of the above (light blue). Hope that helps. :)
So really, to fully answer your question, the easiest way to change from light blue is to buy the game. The other colours are achievable, but they require being an active member in the community and you're are not guaranteed to get them. ;)
Shush, Steve; you're just confusing things. And Juaro is aqua (@Ima, Juaro is someone who won a competition that allowed him to get a custom name colour).
