To avoid issues, only site staff can update thread titles. This is why we advise it best to NOT include a price in a Trading Post thread. But, if you do need a thread title changed, use the "Report Post" icon (which is on every post on the site) on the first post of your thread and list the reason as asking the title to be changed. Be sure to be specific as to what you want it changed to. When a member of teh staff sees it, we will change it.
