We are trying to make things simpler to users BUT we need to have some expectations:
CGN is more like a multi-tool, classified site is one of the tools. The back end of a forum is vastly more complex than a "post and delete" classified site. The content of "classified sites" are disposable, but Forum like CGN and Reddits have to retain a lot of materials. We are like a library, and have to keep a lot of things around to be useful to members. The library gets bigger and bigger over time, versus a classified site constantly has turn over.
