I am going to install the private message hack to my board, but in the database there are 3 versions (1.5c (which says it's update to 2.0 and points to a broken link), 3.8 and 3.5b) and they are all pointing out that they are based on CYMPM by Mutt, whatever that is...
What version should I install from scratch, can I immediately start with installing version 3.8 and following those directions?
