Hi, I have a personal website and i know only limited HTML
but i came across this site and it looks awesome

http://www.servletsuite.com/servlets/cobrowse.htm

i want to put this cobrowsing option on my site, but i dont understand how to do it!
if you can tell me where i can start learning about how it works or you can explain it to me that would be awesome
or you can tell me its just to complicated for someone who knows limited HTML...
thanks!
