The only way to get rid of an article is to hit the abuse button and ask one of the moderaters to pull it. They may or may not do so, depending on your reasons for asking, etc.
The forum has a page that lists the latests posts. Every time someone replies to an article it goes to the top of that list. Thus, when I replied, I bumped your article to the top of that list. This is why we use the the terms bump and bumping when we don't really have anything intelligent to say, but want others who take a look at that list to see this post.
Also, you will note that there are a couple names typed into the "to" box. By putting their names in there they will see this article when they do their self search, and if interested they will come read it. I keep a list of names for posters who at one point made the mistake of asking to be on my list, and I bump them to various articles.
