My thread posting titles are not in bold?

Just realized that when I place an ad the ***le is not in bold as are the ***les of other ads placed in the same category. Just wondered why? Thanks

 

@corndog It's because you have already viewed them so they shows as having been read (no longer bold). Just like with any other thread once you view it the bold goes away until a new post comes up and because no one can reply to ads it will never reset for you back to bold because nothing is new unless you sign out and sign back in. It is bold to everyone else until they click on it.
