My other forum has PM and limits the For Sale section to members with 30 days membership.
However, I actively encourage all general discussion to be only in the main threads, as PM's are a PITA to answer over and over again.
PM's should be carefully and politely used.
I don't post much, but I do read a lot here.
This is a great forum.
And my van conversion friends would use a trailer next time. Easier

to live in a trailer while the motor vehicle gets repaired...
