Try this PR Prediction: http://www.iwebtool.com/pagerank_prediction I don't know how good it is though.
PR prediction tools are never accurate. Anyway Vince, as other members have already said you need to do 2 things: Add more unique content that you've written - try and do this as often as possible. Get more backlinks to your website - this can be done via link exchanges, directories, paid links, etc... Do those 2 things as much as you can and you will get PR sometime in the future. You shouldn't worry about your PR as much as the 2 things I mentioned above. PR is useful when selling links, or your website so unless you're thinking about that (which I don't recommend yet) then forget about PR. P.S. Get rid of that ugly Amazon affiliate ad on your homepage!!! The "Store" link is fine but don't make the first page visitors see of your site ugly like that!!
!!! There has been a couple PR TOOLBAR updates since Nov 2 in quick succession. Buy a good book / decent website and read. Good here ..But lots of mis information IMHO Jay
