Jane,
Welcome to the forum
It's no problem, a moderator will move it (I don't think we users can move things).
The distinction is that if you are posting your own trailer
for sale, you post it in the "Trailers for sale or rent" section; but if you are posting a trailer for sale that you just saw somewhere, or that someone else has up for sale, you post it in the "Referrals" section.
But like I said, no big deal, and Mod will move it, I'm sure.
Again, Welcome!
Raya
