How do I change a 'for sale' prefix

[fridge]

Just sold the bike I posted, tried editing the first post but I can't see how to change the 'For Sale:' prefix to sold. Can you point me in the right direction please?

Cheers
David

Just for reference the OP should be able to change it themselves by clicked EDIT on the first post, then select GO ADVANCED and the forsale/sold/wanted tags should be next to the thread title
