Jasper is correct as shown here:
The originating poster of the question can then rate all the replies with the "best" answer yielding 4 points to the responder as well as marking other good (aka "helpful") replies yielding 3 points to the responder. So if someone wants a LOT of points, they give lots of answers and hope they get rated Correct or Helpful.
In regards to my question post about...Insiders, where are you?....I have purposely left the question as unaswered because I am of the hope that fellow Insiders will continue to respond with their travel adventures and we can get some discussion to revolve more around what we are mostly here for and have been here for....travel issues, insights, adventures and advice.
If you feel that the question has "not yet" been answered, then, yes, don't respond. The idea would be that the questioner leaves it empty as replies come in that aren't quite solving the problem. The questioner can always clarify his/her issue to aid the folks that are trying to be helpful, but......if you click that it has been answered, you're signaling problem solved.
