Hi, Worked on Pagerankster for some time now, and I think it's ready to be in the tools section on DP. With Pagerankster, you can look up your pagerank, or.. you can lookup multiple website's PR at once (think the limit is on about 1000 lookups pr. query, but that's because my server times out then *lol*), you can also register and sign up for PRchart, which let you add all your websites, and view a graphical chart of your PR's development over several months, and you can get a mail when your PR changes. Check it out at http://pagerankster.com
It seems to work nice but you should add more services to get it worth visiting. The e-mial notification is a good think
I will soon release a complete website analysis, that you can combine with PRchart. If you use it as standalone, you can get alexa rank, backlinks and more on one site. When you create/edit a site in PRchart, you can select which info you wan't on a specific site, and then you can view that info in your site's overview in PRchart
Hey The release of PRchart 1.0 is excepted to be launched this weekend (Saturday) with new features (backlink tracking, keyword position, new design and more).
