I think it isn't a big deal to have a couple week moratorium with a top line highlighted statement on first page clearly making it obvious that the moratorium is temporary BECAUSE as stated, you want to encourage people to look back at threads that were often well presented as a question or point of interest, but got too little response because they may have gotten lost in more superficial but fast moving threads.
I personally don't post much these days, because there are newer posters that have their own exciting new GCA discoveries that they are anxious to discuss, yet may have been covered in years past where as an older poster I already offered my views, and it is more fun to see newcomers first realize some particular thing. Not to say I or other older posters know it all, far from it. Just that the redundancy seems to me to be a drag on the newcomers enthusiasm. And, I must confess that I find myself forgetting details I used to know a bit about and have forgotten from atrophy of the brain, not using or applying learned tid bits in the real world. So, why clutter up a discussion between currently knowledgeable people on matters like turf science practices, or construction techniques between actual professionals doing in real time. I prefer to ask questions when something is said that I might have come across and and someone's new observation triggers a thought.
I still wish there were a direct photo posting function like people can post to Facebook or other social media directly from your own computer's photo gallery rather than a web photo hosting site. It could be managed with an accompanying well thought out policy that if the poster starts posting too many photos that become less informative of the GCA involved and more about one's excellent adventure on a golf trip.
I wouldn't discourage the friendly meet-ups threads that take place and get organized here. I think it is vital to have the secondary outlet of actually getting together niblick to niblick at some of these courses that capture our imaginations, to really solidify the collegiality and fellowship that exists on this site, like no other site I know of..
