my method of link building on high page/keyword website

hey guys

i have a forum which has 52 seprate forums which all have their seprate keyword.

i am currently posting on domain pr +1 or high to each 52 forums with seprate keywords. only posted 19 atm.

would it be best to post just to main forum for top 3 keywords? i do need all forums popular as possible but. maybe i am trying for to many too soon?

is posting pr+1 domain ok even tho page is n/a?

thanks guys

what the fuck are you using to do those postings.

EDIT: [lol nothing, my bad]
