I voted 1 PM per 5 posts.. The first couple of weeks at LPF, I only used PM, but only about 4 times to contact IgorT about a build. Then for a long time I didn't post or PM.. then I posted for many months, and recently I started PM'ing quite a bit. I don't chat that much however - if I want to have a nice conversation rather than simply asking for help/arranging a deal/helping someone else (even though these can be nice conversations too), I prefer chats such as laserchat.org and live messenger.. Or preferably face to face, but that may be difficult since I believe only one or two other members are from Denmark
considering the several hundreds if not thousands ive already deleted(mostly from the old forum) i cant say for sure but atm the moment i have 509 pms in my inbox..
