I am generally quite open to creating such a section, however most of the time I just use the "all unread posts" link so view all the threads in one place. Our current approach has been to identify common topics and create a section after the fact (and move existing threads there if applicable). I'd rather have too few sections with more topics than idle sections. So please feel free to start car audio topics wherever applicable (e.g. general or DIY section) and if enough of these discussions accumulate, I will create a new section and move the existing topics there. Does that sound reasonable?
