What does it do? Take a look at RateU's forum for some nice ideas of what it can do. I also have some more basic examples here of what can be done with XThreads. I'm pretty sure there are many other applications of this plugin, but those examples just give you some simple ideas.
The basic idea is giving you the ability to define custom fields for your threads, and providing methods to give you a lot of flexibility with customising forums.
Warning: I'm not going to bother with "beta" labels and so on. I've done some testing on this myself, but it's by no means extensive. Use this at your own risk.
Installation Instructions: standard installation procedures apply - you can find them in the announcement here. You may need to CHMOD the uploads/xthreads_ul/ folder to 0777 after uploading the files (probably won't though).
Known conflicting plugins - MyPlaza Turbo - If you are using MyPlaza Turbo, note that the author decided to use a particularly odd method to implement certain functionality, practically destroying compatibility with any plugin which hooks into the forum add/edit routines. I've included a patch to address this issue - you need to replace inc/myplaza/myplaza_admin_plugin.php with the following file (it's unlikely that this will be committed as the author has decided to discontinue development)
