I've been using Roblox since approximately 2008; and I've seen a lot of the changes made to it since then. I'm a pretty good scripter for anything that doesn't involve newer subjects such as animation and template places, and anything using incredibly complicated math function such as the classic LightCycle script by StickMasterLuke.
In non-Roblox news, I'm going to be going to college for a degree in Computer Science starting in 2014, and I've been programming stuff outside of Roblox for a couple of years now, including FRC Robots; so I consider myself to be somewhat of a veteran programmer.
