Howdy rpm and co.
mybb.bot's a nifty lil' tyke, what with his spurts of posting the new classified ads on the forum. However I've also seen these posts generate a whole lot of noise with the "how much" posts they invariably elicit.
Might I suggest that you include a price in mybb.bot's posts and preferably also have his posts include a prominent "CLICK HERE FOR MORE DETAILS"-link pointing to the relevant Classifieds ad? I'm sure it'll save a couple of dozen useless posts a year.
