Low Page Rank

I have been working pretty hard on my site for some time. My page rank is horrible. I have done a lot of custom work reading from this site. We are somewhat niche, but I would expect higher than I have. How do I go about tracking down the cause of this. It seems like its voodoo

99% of the sites have the same issue. I get nearly 10k visits a day from google alone, yet i don't have ANY pagerank.

ignoring it is the best thing to do.

For forums, I would only expect a low PageRank *distribution*. Most of your pages will have low or no visible PageRank.
