I don't know if this is a temporary problem or not, but upon multiple tries to use the main site a pop-up appears with the following:
"A username and password are being requested by http://www.itopsites.com
. The site says: "Your site has not yet been approved, please remove the topsites button code, or use only a text link until your list manager has approved your site."
I have to press cancel twice to remove the pop-up, but it appears again whenever I move to a different page on psypoke.
