            System.out.println("errror in applying the theme");
        }
    }

PS: is there any way in this group that each and every mail lands in
my email box, so that i can reply from there itself without coming to
the webpage?
(i don't like the one or two emails per day. i can't wait untill the
end of the day to recieve the mail)
thank you :)
