I have been on D2jsp for about 3 months and the only thing I dislike about it (Other than the lottery lmao)

We post something we have for trade, or we post something that we're looking for.
Then we get that said item or sell that said item, but we continue to receive private messages about it!

I don't know if this is possible, but it would be really cool to be able to close your own thread, to inform other users, that you got what you were looking for!

Let me know what everyone thinks!

No

You have the ability to edit your first post up to 3 days from the time the post was created or last edited, as described here.

Simply update the first post when it has been sold. This has been suggested in the past on several occasions.
