I used to post a lot on this site; you can still find most of my posts under user641

I'm going to stop posting here for a while (though I still like seeing the inventive and creative questions and answers). I think this site has a real problem with deletions, both from poor question askers and over-aggressive high-rep users. I hope this problem gets resolved.
