I haven't noticed many at all on the 47-59 forum where I spend most my time. I've actually posted one that was a killer parts deal for somebody up recently in the 47-59 forum and it looks like another member is glad to have seen it and is acting on it.
Maybe other forums I'm not in much get a lot of it?
I don't know if I would like them as much in a separate forum unless the titles had the year listed. And I agree as they age the ads are gone but by then they are pretty quickly down the list.
We have them separated on a motorcycle forum I am on but the whole forum is for just one particular motorcycle brand and make so its easy to separate
Even technical data gets pushed down the list by other technical data. Just the way it is. I have no idea what is on page 4 and beyond. I just do searches when I need specific info. Sometimes it takes awhile to find what I want because there is years of good stuff on here lol
