If your posts are popular and followed by many members, request your own board so members can easily follow your threads. The only condition is selling is forbidden. It is not a platform to sell systems.
Simply create a new thread and add whatever you want to it. You can post links provided the content is 100% original and not published anywhere else, and your article is genuinely informative. Blatant spam with repetitive and useless information will be removed.
Find other professional players here. Once you find a potential partner, start a private conversation that nobody else can read. I suggest do this off forums completely and with encrypted emails or chat. NEVER reveal your real name or any personally identifying information.
