If I redo my site will I loose PR?

[Fryman]

I couldn't decide on which forum to post this, so if it belongs to another one feel free to move it.

This is my question: I have a website that sells paid submissions to some engines. I want to change the whole site, it will now offer free webmaster tools and free submissions. Will I loose my PR? Is PR dedicated to the domain, or to a specific page? I have noticed that the homepage has a PR of 4, and several other pages have a PR of 3. So, if I change all the website, will I be able to keep at least the PR4 that my homepage has? I did a link popularity check and my homepage has 25 links pointing to it.

Kind of a newbie question, but I am very confused and could use your help.

you won't lose your PR

You won't loose your PR but if you adjust the page, you might start loosing some search engine results. I lost about 3.5/5ths of my search engine traffic for one of my sites by changing the order the page was in (granted that it only got 100 people per day)
