It's a little more complicated than that. A namespace is like a category name indicating where a page belongs. For example, the Help:Editing page has the namespace "Help" indicating that the page belongs to a category of help pages.

For the Trading Posts, the goal is to have something like "Trade:Trading Post" in order separate the page from the main namespace so that activity on it can be separated from the activity feed. This new namespace isn't currently a part of the wiki, so we'll need to request it after a consensus is reached.

This page shows more information on namespaces, and how they work.
