Back links from the same site ?

How to have more back links from the same site for example pls check this site uncoverthenet.com it has PR 8 and most of the back links comes from the same URL

http://www.google.com/search?hl=en&lr=&newwindow=1&c2coff=1&q=link:lUoIHbhQEBQJ:www.uncoverthenet.com/

How do I do that ? This is not the only URL that I saw this there is a forum site they have PR 7 they too have more back links from their site than other sites,

What is the trick ? how to do it ? please explain.

 

oh just checked forums.digitalpoint.com that also has more backlinks from the same domain.

I am sorry I didn’t get that , How to do it for forums?

 

so having links back to homepage will add it as a back link ? I think I am missig somethig there ?

 

You can see this guy hosthideout.com has no back links from his own site.
But he has links back to their homepage. so there may be a trick?
