I know I am late to the game here, but the forum should be an extension of the LZ/club in general.
I can show great intelligence when I am working on the car or in the attic doing HVAC work, and still frequently my wife shows even greater intelligence. However, one day some time back in the LZ when she was waiting for me to land she told me that a group of pilots were having a very loud discussion about how F-ing rad the day was and how F-ing cool the conditions are and did you see my F-ing zoom coming in to land, etc, while there were multiple visitors with their kids in the LZ. She was so embarrassed for the visitors she went to the car and waited.
I tell everyone I fly with (737 flying) about hanggliding and many of them do go to the CSS website to look around, being pilots after all. If a visitor who is potentially interested in learning to HG/PG goes to the website and sees foul language and general discord it is quite possible we have lost a new participant, especially if said newbie has a wife and kids and plans to bring his wife and kids with him so they can enjoy the activity as well.
While I have no problem with intelligent people and even showing my intelligence, the forum and the LZ should be welcoming to non-members so that we work to bring in as many folks as possible to HG/PG.
