I added prefixes to three more pages. Only looked for threads with attachments this time to speed up the process, so I might have missed one thing or the other.

What would help make this easier, either a button for Moderators to directly set thread prefixes, or a possibility to directly go to advanced edit mode without the simple edit mode (where you can't edit titles) in-between.

Oh, and also, the order in which the thread prefixes appear seems to generated randomly every time. They're not at fixed positions in the list. Very strange.
