Now that we've upgraded the forum software (see announcement), we have the ability to define thread prefixes, which appear in front of a thread name in the forum display, or at the top of the page in a thread display. Prefixes help classify threads within a forum. Unlike tags, they are selected from a pre-defined list. Here's how thread prefixes work: The forum administrators and moderators will decide what thread prefixes make sense in what forums, and make them available. When you create a new thread in a particular forum, you may see a drop-down list with prefix choices in front of the thread title. You can choose one if you like, or let it default to "no prefix". If you go back later to edit the first post in your thread, you can change the prefix if you click Go Advanced. All users see the thread prefixes in forum and thread displays. Where prefixes will be used Our first test of thread prefixes is in our Marketplace forum, which only eligible users can access. If all goes well, we'll be looking for appropriate uses of thread prefixes in other forums. We haven't yet decided where else to use thread prefixes, and your suggestions are welcome. For example, perhaps the Mac OS X forum would benefit from thread prefixes that indicate that a particular thread is specific to Lion, Snow Leopard, Leopard, Tiger, etc. In addition to suggestions, we'd also like to hear from you if you have any trouble with the thread prefix feature.
