Well after looking through alot of html pages today I found some interesting thing to do with input boxes, now within your input box you can tell it to set autocomplete = on or off.

Well its not the discovery of the century but it is good if you have a password retrival page on ur site and you dont want some kid trying to get the pwd by knowing the email address or whats so ever that pops up out of autocompletion.

Ahh well...

seeems to me like you didnt' know them before by the way you talk. by the way, the input boxes in UGN are pretty good designed.
