I understand, no problem, you will have pm in a minute.

Thx for the URL.

What i still don't understand is why you want to close all threads. Why not just set permissions to disallow posting in this forum as it only contains "closed" threads?

or can you set the forum to show more threads per page (say 200) then select all and lock, repeat till all done

then set it back to whatever you had before (threads per page)

Marco, I just explained why my friend want's it closed. The forum part is already closed for posting.
But if users do a search (mostly via google) they get in that forum part, don't pay attention and see later that what is in there, is already sold. If the post is closed, they see faster that post is closed and have a look further.
I wouldn't mind myselve, but my friend just would like it that way.

But he has them closed now, so if he keeps it up a little, he would not need a mass close.

However I could imagine maybe something like this would be nice to have when people are replying to old post, which they get to by googling on something.
You could archive them, but you could also then mass-close if laste reply date is older then xxx, or something like that. This way one does not have to mass-move posts to an archive section.

I have a tracker on my forum, and people so often hop onto torrents that they most likely won't complete because there is no seeder, so I have a plugin which adds a line to the first post if there has been no seeder for 2 weeks - a big warning in bold red. Perhaps you can just add a plugin which adds something in the postbit at the top of all first posts in that forum - "THIS ITEM HAS BEEN SOLD".

That would be a nice idea too Lynne. I will suggest it to him.

That could be done just based on the forumid, or hide the reply button in that forum. Sounds to me like a better idea then close all threads.

I will suggest all options to him. Thank you all for the tips and idea's.
