I assume you're referring to Free Web Directory I am seeing PR2 as well unfortunately. Your other directory is showing PR4. Ours are holding steady
indyguidedotinfo, my blog also dropped from pr2 to pr0.. the blog is listed under Recent Blog here on dp next to my name. I believe it might be because google is starting to penalize such forum linking strategy. I hope I am mistaking.
Google seems to be seeing things these days so expect that there will be more and more. Algorithms are really getting vulnerable and the Google dance doesn't seem to stop.
