Thanks in Advance for your kind words.
Second - PR4 and above page links show
Third - Google only shows a sampling of backlink above PR4 and not all... but this does does mean they are not included.
I wouldn't concern yourself with the "number of"... as the volume isn't as good as the quality.
This is wrong! Google has been showing PRO and a lot of links under PR 4 since the last 2 or 3 backlink updates. In fact, for many people the high PR backlinks are not showing.
You can not count on what Google is showing for backlinks. Get your backlink count from Yahoo.
