Here's some sample copy - does it say what we want it to say? If not, any suggestions?
NOTICE TO SUBSWAP SELLERS
It would be a big help to everyone that once your item sells, you would come back to your post and edit the subject line to have a big SOLD - so people don't waste time looking at items that are no longer available. It will save you time in answering inquiries too!
So "32nd Parallel Type VII ready to run - $2000"
"SOLD - 32nd Parallel Type VII ready to run - $2000"
