Oh you posted that on another thread!!!

As i understand it the latest version of wordpress has the widgets tool already installed so you dont need to install it. I use 2.2 and it works pretty good.  Having said that i edited my template to get adsense to show up

The latest version (2.3.1) seems to be very buggy.
I did a custom theme for a client on my test blog using 2.2.3 and when I installed it on his site I used 2,3,1 and the widget function disappeared.
Had to do a quick uninstall and reinstall with 2.2.3 to get the widgets function back.
Haven't touched 2.3.1 again and won't till they fix the issues with it.
Also many themes and plugins won't work with 2.3.1 and that's just the start of the problems.
The only way to use it that I have found is to use it on a fresh install and then search, search, search, for compatible themes and plugins.
Way easier to just use 2.2.3 for now.
By the way you can still find all versions of wordpress at

Alexa is 'as much use as an ashtray on a motorbike' - Alexa is basically spyware and the traffic it reports on is based entirely on one thing - searches made by people who have their toolbar on their browser.  The pagerank of a blog is also of no use - blogs change daily with input from outside influences including spam posters that need moderating.  Most of the input is based on anchor text of the page which is good for internal pagerank but if you are thinking greenline toolbar pagerank then that is artificial and should be ignored.
