I just upgraded this site to WordPress 2.1 and I repaired the documentation and forums. Please report any further problems you have with the website via my contact form. Because my policy of letting people sign up willy nilly had been abused, I have restricted registration now. If you would like to write an article about phpFlickr or about an application using phpFlickr, please contact me and I'll send you login information. To clean up the system, I deleted all user accounts who never wrote a legitimate post.
Hopefully I will have a new version of phpFlickr out some time next week to bring a couple of new API methods into the fold.
