Just click the screen to log ON (note the difference between log in and log on) and click the blue button to log in if you already have an account. Click the grey button and it will tell you your ID Code which you tell the log in button. WARNING: Memory Match doesn't work yet so don't even click it. Please, if you have time, look at the Memory Match code and tell me what to do (if you know) to fix it in the comments so this Scratcher Hangout isn't so boring.
It was all made by me, but I got the buttons and the cat from Scratch. I did write Log In and Sign Up on the buttons though. Memory Match (the matching game that isn't working yet) was made by @Maythorn and I edited the sprites.
