adding more sidebars

if ( !function_exists('dynamic_sidebar')
|| !dynamic_sidebar('nameofsidebar') ) :
 endif;

My sidebars don’t have names (?)

Yes they do. Look at the codex.

This will create 2 sidebars named “Foobar 1″ and “Foobar 2″:

register_sidebars(2, array('name'=>'Foobar %d'));

You then have to insert the code via the code thee17 gave you. Put the code wherever it is that the sidebars need to load. Your theme should already have a live much like the one thee17 gave you. Find it. Its probably in your header.php or your footer.php, but no promises. By the way, its in the codex.

If it were me, though, I’d give them names on purpose so that they have some kind of meaning as you work with them– top-left, bottom-right, that sort of thing.

PS I just discovered for some REALLY weird reason…
my site only loads when you access it as :
http://vaisnavi.org/v3/

it is totally blank when access using the www. bit in the URL
(this is in all browsers and yes Ive cleaned my cache)

This is more of a server configuration problem than a WP one. Maybe see this thread.

this new wordpress is just TOO buggy for me

Or you aren’t reading the codex.

okso following te instruction given in that Codex tutorial age
I cut and paste exactly as they had it on their site
I uploaded the file]\hit refresh and the whole site was gone blank.

Then you did something wrong. Its hard to say exactly what. Cutting text from online and pasting into source code is dangerous, for one. Sometimes it works. Sometimes it fails. Somehow, you introduced an error. Try to understand what the script does and then recreate it, rather than just paste.
