I was using this tool (http://www.rankalert.net/backlink-watch.php) yesterday to check the PR of the pages that link to my site and the tool was working well and was showing the PR of these sites accurately. Today however all of the sites come up as being PR0 which I know is not accurate. I was wondering if this was the same for everyone? I have tried to contact the webmaster to ask him but the contact link doesn't seem to go anywhere.... I have a lot of use for this tool providing it is working so I would be grateful if anyone can offer a suggestion as to why it has stopped working Thanks
