The first thing I do when I see the notice from the Whistle Stops is click the upvote button  and then I try and respond with a comment if I have the time. I have always felt that I need to support the group any way I can and I just don't understand why everyone doesn't feel the same way, an up vote costs a person nothing to make. To me it shows that there was at least some appreciation but like I said, I watched for about  a week straight a while back and not one person on several days upvoted the Whistle Stops even though they were featured in it. 
I wonder if it is because some folks have so many groups they belong to and this might be as not as an important group to them?
Thanks for following the suggestion on the SBI share, I think it might be a good thing to consider going forward as a "one time" initiation fee or even an application fee at sign up. 
It will be interesting to see how many folks actually step up and donate a share since the suggestion has been made . I have received some responses  that people have done so, so that is encouraging but no where near the numbers I would like to see yet.
