Now that the forum is opened up to dealers I think this problem will multiply.
If a pre-determined length of post is set, it would make notice to the poster that re-submission may be necessary.
I would think that since most are trlrs that a 90 day/3 month listing would suffice. Perhaps shorter for dealers, 30 days.
I also think that the posts should be kept for the same reason stated in other posts but locked down for info only.
But, most importantly, there should be parameters for forum membership AND sale submissions: ie: LOCATION .....COST of item.....CONTACT INFO
These are the 3 most important items for a sale.
I also belong to several forums and this issue comes up often.
No one should have to post, to find out WHERE something is located, or how much the asking price is. And it happens often if parameters are not set.
