I have linked to a bunch of relevant sites from LinkPartners.com members and so far so good.
*I am not an actual member and do not use their link management service though.
I did manually check out each site they recommended and some of their members have some good
PR happening so I guess it's ok.
There's also some sites that have no
PR in their directory. You just need to manually check each and every one out first and pick the good ones.
I also noticed the actual link pages generated by LinkPartners.com for their members have
PR as well... as per their claims.
The real clincher though is the fact that my link pages that have LinkPartners.com members links has gained
PR since I started linking to them.
