Stats are misleading.
I never shut down my laptop and I leave it on for days with some pages open inclusive of the org (yes, you guessed it right: I run Linux, not Windows

)
As someone who just observed this site for long but only recently joined actively and someone who visited nearly every www 70's Mercedes forum in more than just English language, I can safely conclude that w116.org does have moderate activity on topic (far from dead, like most others) and, most important, majority of topics are
not on three least helpful subjects: where to get common parts - again and again, how to pimp and how its pimped, what radio/speakers/amp/woofer/tweeter etc.
My observations:
Is it helpful? Yes (4/5)
Abundance of spotless knowledge? Better than most (3.5/5)
Provides solution or solution pathway? Yes (5/5)
Are there people wiling to help? Plenty (4/5)
Is it welcoming? Yes (6/5)
For comparison, Benzworld 116 forum is dead past pimping and radioing and it's only clinically alive. BW's 107 forum may provide faster or more in-depth answers for many a problems but given that w116 has significantly smaller members database, it stacks up fairly high.
So... well done.
