Your selling seo in your sig & your asking a simple seo question like your not sure what's going on?

Nice...

There is no point creating stupid threads just for the sake of increasing your post count..
Try to engage yourself in Good conversations rather then just fooling around,,
Google updates itself every 2-3 month, they have not set up a date for there next change..

Read seomoz Blogs and u will get the idea...

I wonder why people are running behind PR...?
Google itself confirmed this thousand of times that Google is least concerned wit the PR... and there are many other performance metrics to focus upon.

go find some other forum to spam...

Not a good effort to increase post count.

Last update was on 4th August. In past weeks there is Pagerank update for internal pages.

Thanks
