In order to avoid increasing the amount of SPAM that I get, I obfuscate the email address on my web page. I do this in a way that spammer programs won't recognize it (at least not correctly), but such that it is fairly easy for real people to easily obtain my address. I do this by writing a one line shell script (minus the first line hash-bang thingy) that prints out my email address on the screen.

If you just cut and paste the line
echo arjera@zngu.hgnu.rqh | tr a-z n-za-m
into your favorite terminal program then my email address will appear on your screen.

For the curious (or those stuck without a terminal program), all that one line program does is decode a simple elementary school level encryption of my email address where a's become n's, b's become o's, c's become p's, etc.
