Documentation Problems → Link is wrong
Several of the links (for instance on http://getpopfile.org/docs/faq:pseudowords) refer to the page "The Spammer's Compendium" (http://www.jgc.org/tsc/) that hasn't been right for years. The correct link is http://www.virusbtn.com/resources/spammerscompendium/index (check archive.org to find that an intermediate step was http://www.jgc.org/tsc.html)
Thank you for reporting this problem.
I have fixed the link on the http://getpopfile.org/docs/faq:pseudowords page.
A wiki search found another out-of-date reference but it is in the release notes for 0.22.0 so I have left it untouched ~ that page just displays a copy of the release notes and the link is not clickable.
