hey guys, I know it sometimes happens that PR can drop and it just to be a glitch or something, but yesterday my site (Micromail - Homepage - Software Licensing - Computer Books - Windows Vista - Office 2007) dropped from a PR 6 on its main page to a PR 0. It then went back to a PR 6 for a while and now its stuck on PR 0 again. Every other page in the site has gone to PR 0 aswell and although im sure its nothing to worry about its starting to unnerve me a little now. Thankfully we're still being indexed and our SERPS havent been effected, but I cant think what could have gone wrong. Ive checked multiple datacentre sites and they all list the page as PR 0 with the exception of one or two who list it as a 6. And im guessing its not a PR update so whats gone wong? Any help much appreciated!
