Answer: Search article marketing in fr*ee forums. Just be choosy about the forums you search.

Don’t think you can become a member of every forum listed. Forums are communities, and hanging around more than 3 of them makes you bad company. You’re never more than an acquaintance when you hop from one forum to the next. Pick 2 or 3 and hang out the way you would linger at Starbucks. 

When joining a forum, make yourself known. I think forums are a bit like business meetings in the office conference room. Most of the people in the room don’t have a lot to say or when they do, you’d rather they didn’t. Forums have the same limitations. 

After registering and introducing yourself, search the subjects that matter to you (e.g. article marketing).  Scan posts looking for the best answer to your question. Respond to the person making the post, add a comment relevant to the discussion, and leave a compliment for the person who teaches you something new.

In time, you’ll initiate threads and newbies will learn from you.
