I think after implemetation of "SEARCH" on old posting, one point in Peters posting (or his demand) to check in previous postings before post a new subject is quite right.

So we request all new comers, rather a Banner should always be shown on the site, which says or encourage that should see old postings before launching new query.

Like any thing these postings also sometimes has something new, maybe the application of some particular routine etc, which was not known so far to this message board.

In my opinion, let this site as it is, and have some message shown on the board saying "Please check the old posting before launching a new subject, You might find solution to your problem quicker"
