Sitting on the Boards is not a 'private' forum. Although only members can post here, it's open for anyone on the internet to read. So if you're posting about personal, children, coach issues, or contain video it would be better to take it to one of the private forums such as On Ice Training, Videos or Watching the Zamboni. Look for the "members only" after the forum title.
I've noticed a couple of people tend to post stuff about their kids here. Even though it's anonymous, it's worth considering whether you want that available to internet search engines.
