Note that the site requires registration. You can use:
Userid = freenet
Password = freenet
If that fails, go to Bug Me Not to get another ID and PW. BTW, you can use Bug Me Not to get IDs and PWs for thousands of sites.
Looks like they checking to see if you already voted by login, so I had to find my id... could not resist trying to bring that rating down a little.
Thanks for the Bug Me Not link!
