The classifieds section will be developed into whatever we need it to be. It is already possible to have a discussion in the q&a section, but we might "reformat" this to another "discussion-like" format, so that the questions are not "hidden" in a q&a tab.
There are other apparent advantages with this format when it comes to what kind of info every ad should require, that is impossible to format a forum post to. So I understand your concerns and these will of course be taken into account.
The classifieds will also become much more visible as soon as we close/redirect the current links to the different areas in the trade section.
Well, there is a "Mark Content As Read" at the bottom that you can use. I'm not to comfortable with the way the navigation runs right now, as I have also been used to click "Mark all as read" when I was finished, so I'll be looking into if there are some changes that can be done.
You can always just download the latest version. Don't use Chrome that much but it pretty much auto-updates all the time.
