Doesn't seem to work anymore :(
Reshared because I can't tell where the problem was. Only the first (current) viewer was displaying on the list (and the data), I was trying to fix that... - Apparently, cloud data character limit is 256 now. Improvement of 128 characters, yay! (It has been for some time I think, but I just learned about it today.) This project uses cloud data to get a list of the usernames of its five most recent unique viewers, in order of when they viewed it - and you won't see any repeated usernames, all 5 of them should be different. I've tested it, and it seems to work! I hope... NOTE If too many people are using this project at one time, the cloud data might get corrupted and save incorrectly. I think. I haven't tested if this is true or not, for obvious reasons. HOW IT WORKS In the split second after clicking the green flag, the existing cloud data is decoded to a list of viewers, and the list is updated (adding your username to the top and kicking out whoever is at the bottom) and encoded back to cloud. Encoding/decoding: each character corresponds to two digits (i.e. 00, 19, 08, 32, etc.) and the digits "99" are reserved for telling the project when to move on to the next list item. When encoding, the characters are converted to the digits, which can be stored in cloud variables. When decoding, vice versa happens.
