PM is a tool to talk in private about some thing with one user( off topic). They are more like emails to a user. Questions like how do i do this? where do i get this? replies to post made by a user go into the open forum.
hey dude where do you live? etc are more PM topics.

here are a few tutorials if you were trying to post but ended up sending pms

this message is in response to many PMs i have been getting which need to be in the forums not as PMs.
Dont get me wrong i like to help, but its better in open
