I've been part of forums before, and they often make you feel invisible, with just one or two friendly folks. Even on small sites, like a niche one for long-distance drivers with around 50 active members, it was unexpectedly hostile and unfriendly to beginners. I eventually gave up on it. Community matters, as does a positive online environment (PON), and I miss posting when I can't be online. While I may not know many well, those I feel acquainted with are the ones who contribute to making this site a welcoming place.
