Late 2010 here! Would've been in middle school at the time. I found out it while I was roleplaying anime characters with my friends on Formspring. Listened to Sunslammer once and my life would be forever changed as a result. Spent most of my days either blogging about it on Tumblr, RPing fantrolls on Formspring/Zingled chat/Trollmegle/FB/MSPARP/Cherubplay/and-so-on, cosplaying at local cons and park meetups, and lurking on the Skaianet imageboard (now MSPABooru). If you dig back through the archive you can still find some of my first attempts at sprite edits there too.
