This could certainly be useful in a number of situations, for example, letting a group of musicians know about a new tune you'd like to play when you get together next, or sending out a new tune to students. To keep all those temporary JPG, PDF, ABC, and MIDI files from filling the server hard drive, they are automatically deleted 20 minutes after they are created. Please don't e-mail me asking if I have a certain song or tune. If your ABC file doesn't come out right, it's probably not complete or has mistakes, or maybe it's due to a bug in the software doing the conversion. Either way, sorry, but I can't do much about it.

Yes, but just to maintain very basic information necessary to make the various features, functions, and security work properly. It is possible to make a site like this work without cookies, but it's a nightmare and requires a lot more programming and makes the site a lot more difficult to maintain, so please just turn on cookies in your browser if you have them off. Cookies are actually quite safe and have simply gotten a bad rap of late mostly because of misinformation spread in the popular press. More than anything else, they are simply an extremely useful tool for web programmers and allow for dynamic and interesting web sites. Maybe Windoze 4000 will be as reliable as FreeBSD from 1998.
