It is a good idea, as a way to encourage those that join that page add some good content here.
In facebook world there are a lot of short comings and using their search function to find past posts is an effort in futility at best.
Bigger trouble many facebook members don't join organized groups through paid memberships.
What is going on now reminds me much of what on in the 80's and insurance woes.
Tons of "clubs" but then the insurance/liability crunch hit the fan and people just stopped leading trips/outings where they could lose their shirt.
Bring on the mid 2000's and with social media it has taken off again.
It is great for paddling in general because paddling is much more visible now making it easier for lobbying efforts.
In some of these new groups I have seen some questionable practices and it is not a matter of "if" but "when" the #$#$# hits the fan again.
The content/information here is second to none and you can get real answers with out getting multiple responses that certain low end equipment is the bestest in the world.
Then there is the time spent trying to weed out the trolls, I admin a few pages and I actually check their pages.
You would be amazed that some of the more "famous" pages have accepted "friends" from some pretty sketchy "people" which have no interest in the activity.
Then you have the ones when they post have more #'s than content with the goal of directing them to their page.
So lots of issues to sort out, but it can be a pain.
