Completely safe link - trust me!
Since you have arrived at this page, you may have already touched a button like the one above that causes an email message to be sent, revealing your email address without your consent (if you are using version 3.0 or 4.0b1 of Netscape). The button can say absolutely anything on it, and you would only find out when it is too late, by watching the status bar at the bottom of the browser.
In fact, I could have snarfed your email address from this page, without you having to press a button or move your mouse. For an example of this, click here. In addition, I could trigger the browser to send mail when you pass your mouse over a link. For example, if you pass your mouse over the "Competely safe" link above, then it will send mail (watch the status bar at the bottom). Other examples can be found here (uses an invisible link in a frame) and here (uses a blue line).
Note: as of June 1997, this bug has been patched for quite a while, but from the logs it appears that approximately 20% of the people that visit this page still have their email address captured. Too many old browsers I guess...
DISCLAIMER: Unlike the spammers of the world, I don't collect these email addresses. I simply count how many people send us mail. After that RISKS note, I am now getting about a megabyte a day of unintentional mail. If you are thinking of using this trick in your own pages, remember that doing so is immoral.
This page has produced mail from the following versions of Netscape. I have not tested whether it is triggered automatically or results from pushing the button (both are bad), and whether it gives a warning to the user before submitting the form.
