I was wondering why my post to sell my stove has disappeared? It was posted about a month or so ago and now it's just gone.
Listings in the classified section are removed automatically if there is no activity for a post after one month.
Activity is determined by when it was originally posted, the last reply or last bumped.
If you have not sold the item and this time limit is approaching you can either reply to it or bump it without replying. To bump it click the "Bump topic" link in the lower left. Either of these actions will reset the 30 day limit and move your listing to the top. If the item has been removed you can list it again if you want.
While on the subject if you sell an item please don't post it that it's been sold, you can indicate it's been sold by locking it. While viewing your listing this option can be found from a drop down list in the lower right.
