Sound Sitter uses 250Mb of sound files, that you will need to download to your computer before you can play them. Thankfully they only need to download once as they will be cached after that. Dont use Sound Sitter if you have a very small download limit on your internet plan.
Dont forget to stop your computer from going to sleep when nothing is happening, otherwise Sound Sitter will stop working while you are out.
Psst tell your friends, just dont tell any robbers
