Alot of people overvalue PR in my opinoin..I mean, PR doesn’t help you in the SERPS..I mean, having a site with a PR5 pointing to you is better than a site with a PR0..but as a new site, you need to concentrate on getting good, quality, on-topic links to your site..and many of them will probably be a PR0 (simply because its not logical for someone to link to you from a PR1 or 2+ site and receive a 0 in return)..However, you will get some people who will give those to you..for now, just concentrate on getting links from sites that are indexed and are not link farms. also, make sure they are on the same topic as yours..k, im done rambling now
