I'm top poster in one of the webmaster forum. As of now I've 15000+ post in that forum.
Forum is already pr2 and it has many more backlinks, so I hope it will definitely be at pr4 in next update.
And best part is it is dofollow I'm selling my signature space in that forum on per month basis. I've an average of 40 post per day.So, you can expect the backlinks to increase rapidly.
And if you need discount contact me.. 
Though for ordering this package you need atleast 3 websites
