Well, I'm also a member on PHO, and for their threads, you can add a description, which is a small little bit of text underneath the thread, displaying a chosen message. I feel PC should implement that.
Also, I feel, that the owner of a thread should be able to change it's name, for example, if someone had a hack, and wanted to change the name, they might not be able to because they can't change the name of the thread.
