WP 2.3 Yahoo

I am using Yahoo to host my paid WP blog. The initial installation was very easy with the click of a few buttons. I set it for Yahoo to automatically uspdate. Does anyone else host their WP on Yahoo? They say they don’t know about a new WP version above 2.02!
I am just starting to get into Widgets and more extensive plugins. Naturally WP 2.3 seems to be a major change from prior versions according to what you folks said here.

The nice folks at Yahoo told me to tell WP that they would like to know if WP has a new version above 2.02. Apparently Yahoo does know that much about WP. But do you folks think it is ok to start adding tags via Ultimate Tag Warrior which does not work at the 2.3 level or should I just wait till they update? Ok Ok thats what I get for not installing it myself!
