General Guidelines
1.) Posting derogatory comments of a racial, religious, or sexual nature. This includes your username, signature line, and title. Site Staff and Moderators reserve the right to edit these items and to remove your ability to modify them in the future.
2.) Posting pictures* or links to images which contain pornography, nudity+, animal cruelty, racism, or sexism. (Any images of violence which are extreme will be removed and may result in a warning or worse.)
*Posts with images of violence or photos of scantly clad men or women should contain a warning in the title. These types of images will not be tolerated if inserted at random in other discussions.
+Nudity includes any photo which contains a clear view of genitalia or female nipples.
3.) Posting or linking to information on how to make illegal modifications to firearms or purchase illegal items.
4.) Posting comments or links in support of illegal activities including, but not limited to, threats against the life of any living person, doing harm to a state or federal official, or advocating the overthrow of the government.
5.) Posting of someone else's personal contact information (home phone numbers, home addresses, unpublished e-mail addresses, and the like).
6.) Repeatedly attacking or insulting a person in an effort to elicit a negative response. You have a right to disagree, but please do so in a respectful manner.
7.) Posting topics or discussions with the desire to do the site or community harm. More specifically creating topics meant to disrupt the site's day to day management, disrupt member's resources, or disrupt the ability for the site to function normally.
8.) Posting repeat topics with similar or slightly varying titles. While it may seem to be funny, the "spamming" of the community in this manner results in problems for users and management. (Multiple topics on important issues or discussions are acceptable, this only applies to topics which waste resources for no other reason except personal enjoyment or humor.)
