Di, one more suggestion on this connect website...EVEN if i SIGNOUT, on the click of BACK button, i am able to see all the previous browsed screens...i mean that if any user SIGNs OUT< the browser should be refreshed and washed out from the buffer...
hope i am able to make my observation point clear to you....do implement this.

Hi Di, thanks for your response.
I need your guidance...in implementing several READY MADE features/applications that we should be able to run on any website....for example, you have designed this website, with very many features, and i am sure you you must have incorporated certain ready made SCRIPTS, can you help me in this regard!!!! i would be very glad to associate with you and learn.
do respond.
