Contacting other Members

so i hafta post 15 messages to other threads before i can pm someone...

Correct. 15 public board posts that actually contribute to the discussion; not to merely boost ones post count.

I think the 15+ post rule is a good idea for 2 reasons - the anti-spam measure already identified, and also to encourage new members to contribute to AN rather than solely use the site for themselves. That is why the posts have to be useful for them to count toward your 15.

I also think you guys can contribute useful posts to the group - you all have opinions, perspectives, insights and questions that would add to existing threads. A big part of what makes AN such a great place is the willingness of members to contribute to discussions, answer questions and present divergent viewpoints. Be part of the site!
