Most of what gets posted here is visible to the public. Private messages, unpublished pages, and content that has privacy settings are hidden from the public. Private messages will not be seen by any admin unless needed for legal reasons.
Community content is content that is contributed by and for the community. This consists of mountain pages, regions, routes, hikes, and any wiki content on the site. By posting on community pages you agree to freely post that info without intent to remove it unless the info involves individuals names, experiences, or other things that do not pertain to the page itself.
Private ownership is for things like your profile, photos you post, trip reports, condition reports, forum postings, private messages, and status posts.
