Obey The Forum Guidelines
Pay attention to the rules for each online forum. They are different for each forum. The forum guidelines are there to allow everyone to positively benefit from the discussion within the forums. Guidelines about linking to websites, spamming, and self-promotion are a part of all reputable forums. If you decide not to obey these rules you'll likely be banned from the forums or have your account on that website terminated.
Create And Update Your Profile
Your profile is very important on any website you use to market your product. Your profile allows people to know a little more about you personally as well as your expertise in a particular area. Upload a photo, and include a link to your personal website or business Facebook page. Keep your profile info short but interesting. Just enough to keep your readers engaged.
