Hiya Newb! Play by the rules and get your 50 quality posts and the classifieds are yours for the taking. If you're the impatient sort become a site supporter and receive instant gratification.
Welcome to the forum. Keep in mind though, INGO is NOT a sales/trading site. The classifieds are a perk for contributing members. Feel free to join the community and engage in conversations, go to the events that are hosted etc. If your only reason for being a member is to buy & sell then gunbroker or armslist is a better place to be.
