I was just about to post a similar message BUT discovered my rental listing was infact saved - but only after I clicked through a few of the menu selection options on the way to creating a brand new listing (Residential, House etc). It seems only after the site has applied a few filters will it tell users they have got a draft listing saved. I agree - a menu item labelled "Drafts" would be a lot more intuitive. Hopefully this post helps others not get as frustrated as I nearly did.
