By popular demand, I have turned on "tags" for threads.
You can tag any thread by scrolling to the bottom and clicking on the Add/Edit Tag button.
The tags will be anonymous. However, I don't want these tags to be used for excessive trolling. Here are the rules regarding tags:
1) No personal info
2) They have to be somewhat relevant to the thread. Don't add junk tags, and don't add insulting tags just because you don't like someone in the thread.
3) Do not use the tags to say nasty things to/about people anonymously. It's fine if you want to throw in some witty tags that poke fun at people, but don't use them as a form of mindless hate against people you dislike.
4) Do not post repetitive tags. If you tagged something in one thread, don't tag the same thing in another thread unless it's relevant in both places.
