The only thing I've noticed is that when "newbies/junior members" open a thread, in most cases the did not leave any post after they've opened it.
They dont post a single "Thank you" after they got posts with answer to their question or a step-by-step guide with solution to problem they had.
Sort of a posting to get more activity on account.
I replied one post one by one to express my gratitude to the friend who provided help, but the posts were deleted by the administrator.
