I was quite surprised today when poking around DMOZ and found a site I listed there a month and a half ago listed there on a PR3 page. Not much for PR, but better than nothing. I guess from reading these forums, my conclusion with DMOZ is, submit, forget and don't bother the editors.
Good conclusions. Also, 1. Follow the submission guidelines as posted on dmoz.org and 2. Have a great, high-quality site.
