Well, to post well, you should post without derailing, but thats hard to do on this forum^^.
And for the "stop post" part, I think you should stop to answer to EVERYTHING even if you have nothing to say.I mean, sometimes, you only posts "okay" "right" or smileys, and nothing more, just to say like "I read you".Its-not-needed!
.Post when you have SOMETHING to say at least^^.
But besides that, there's not so much to do.
