Are you planing to build backlinks from high pr forums? then i am going to share a huge lists. All the forums are do follow.
Just register on the forums and post 1-2 relavant post and in the signature set your backlinks for your site.
Everyday complete 30 forums then after a month you will get 700 backlinks which will boost year search engine ranking.
Dont spam otherwise your backlinks will removed.
thanks
