yeah..

just goto internet optin...

goto security tab ..

and there is one option or icon for restricted site ..( red icon or something like that )..

just click on that

and it will ask u which site to block ..

just give the home path for that site and just enhoy ..

next time you want be able to open that site ....

but ny one can enable that..

or if you are using windows vista ..

use parent control..

its awesom..

u can even watch which site recently opened...

u can block site easily in vista ..
