Taking logo requests! Tell me in the comments what you want - be as specific as possible! I don't know what you want if you say, "I want a 'Q' for my logo!".
When you get your logo, go into the code, and go into the sprite. Go into costumes, and find your logo. Then, click "Convert to Bitmap". Then, download it by right clicking it, and click "save to local file". Finally, set your profile picture to that!
