Hi! I'm TouretticPolyglot, and amateur linguistics enthusiast. I try to use my knowledge of linguistics to edit language-related articles. The "Tourettic" part of my username isn't an attempt to degrade or make fun of people with birth conditions—I actually have Tourette's syndrome. I couldn't think of a good username, so I put that in there because it's true. I also am a polyglot. I have some level of proficiency in several languages. I can edit and translate articles in the languages listed in the table on this page.
I also do my best to remove any vandalism or false information I come across. Such things should not be tolerated. Wikipedia is a place where people come to learn more about a topic for free, and vandalism and untrue facts defeat the purpose of that. Although there would be no need to remove it if people didn't put it here in the first place…
