I think
@ronsplooter nailed it and to some extent durzel with his TZ observation.
People should research a machine, reliability, search old threads - thats the advantage forums have over say ebay etc.
Again, the community policing works as an idea, with the exception of people’s opinions on certain titles.
To me I think its simple: comments should be allowed, but the rules state only on-topic in the For Sales sections:
Not mentioning names, but what got me irate and expecting the “chafe” as I put it when I listed the Alien machine, is peoples hatred, opinions and views - as I cited - I think its so frankly disgusting how an earlier “WTB Alien” thread was derailed by people who hate HP or the game itself. The OP even stated he knew the issues at the start FFS!
How about a sub forum which can have threads game by game so that people can contribute, this is a common problem, that part is unobtainium, etc etc. I don’t precisely know what good this would do other than newer pinball owners/buyers being able to use it as a starting guide as to what hazrads that title has. The other pin forum has a members thread for each game, and personally this is good and of course keeps hints, tips, new mods, parts etc housed neatly.
You have a valuations forum here apparent, so price discussion should entirely be kept to there And certainly not on a FS post... if a potential buyer posts a WTB with the line “Whats it gonna cost” so be it, expect the drums to get beating.
So to repeat, no discussion on a title or its value should be tolerated in a FS post. Period. I think this actually (in my mind) alleviates
@Paul ’s suggestion of standard Form feilds. If, say someone wants to know something I wouldn’t have considered putting in a FS description - I dunno, something like “what rom revision is it running?’ - would be absolutely why comments should still happen and a very useful for everyone who could conceivably be interested.
EDIT: a block of text saying keep comments on topic - use the ‘report’ button if you feel a reply is unacceptable/unwarranted/etc etc could be a handy reminder in the quick reply area perhaps?
