javascripts that I find useful. They are not my own, but are in the public domain.
It has been said that spam crawlers do not read javascript. A convenient way to hide email adresses is thus to encrypt them like this:
<script>mail("myusername","gmail",0,"")</script>
For an example of its use, see (http://web.it.nctu.edu.tw/~string/).
If you recognize this code as yours, I will be happy to add your credit and/or link to your page.
