Why do you want to use that - i dont think its a good move to use nofollow tag on internal pages. Hope this helps...
Yes, sure. It is a good idea to use Nofollow tag for your Contact us, Privacy Policy, Terms of Use and some other not important pages. So that your page rank dont go to them and remains on your money pages.
You can use no follow tags for internal pages. like testimonial, contact us, TOS, Portfolio and Resources page
I once thought this until someone in another forum pointed out that people sometimes want to search Google for youtr company phone number. I also remember reading a Matt Cutts interview 6-12 months ago saying that Google had changed the rules so that link juice effectively evaporated for nofollow tags. Therefore - from memory - if you have 10 links on a page, 2 of which are nofollow, 2/10s of the link juice evaporates.
Personally I don't use no follow on my internal pages because I want google to constantly follow links and update my site content. Personally I would stick to using no follow on external pages linking away from your site only.
I used to use some nofollows. Now I rarely use them, even on links out to other websites. I can't prove this, but I suspect that Google somehow looks favorably on our linking out with dofollow links to reputable sites, especially to authority sites.
People used to do this, pagerank sculpting... So, say if your page has 'x' amount of passable PR value, and you had 10 internal links, if you no followed 5 unimportant pages (I mean in terms of rankings etc, privacy policy and such like), then the pagerank value you would pass (x) would be divided between the 5 do follow links, meaning they get the extra weight that the no follow links WOULD have gotten, were they not no followed. HOWEVER > Some time ago, Google decided it did not like this tactic, so it acted. What happens nowadays is this: Google will work out the value that is passed through each internal link differently to how it used to. The passable PR value will be worked out by dividing your passable Page Rank by the total number of outgoing internal links (10 in the example above), to give a value per link (x/10 in this case) that value will then be passed on to each of your do follow links... THE EFFECT: This doesn't really amount to a penalty or anything, but what it does mean is that Google effectively makes sure that your do follow links DO NOT gain value from adding the no follow tags to the rest. So, for example if we say the total passable PageRank of your webpage is 'x', and, and you had 10 internal links on the page, and you nofollowed 5 of those link. We willalso call the amount of page rank passed to each individual do follow link 'y'. In the old way of working, the passable value per do follow internal link would be: x/5 = y (again, y being the amount of Page Rank passed to each do follow link) In the NEW way (not that new, actually!) of doing things, it would be worked out thus: x/10 = y I hope that makes sense!!!

Yes you can use nofollow tag in your internal pages which are not so important like log in, register here as search engine robots will not sign in or register to your site.
