About the term "Tags", I realize the ambiguity. It is just a reorganization of the traditional approach. Frankly, it was just a term I used when I first made it for my guild (well before it was DKPSystem.com). We needed different categories, and "Tag" was much more succinct than "Category" or "Section." By the time it was live, I had fallen in love with "Thread Tags" as the term, which is why I try to make sure that everywhere I use the term "Thread Tag" rather than just "Tag."
Though that touches on an interesting issue....multi-tagged threads.
...whoa...seriously, it never even occurred to me. The main tag can remain the "primary" tag, while secondary tags could be for "other categories"
Example: The officers are discussing the hunters, it would make sense to make it primarily an "Officer" tag, while also giving it a secondary hunter thread tag. Ultimately, the secondary thread tags would act like symbolic links (unix/linux file systems for those who don't know what those are).
Oh man...you just made my day, even if you thought it would spark a holy war.
Yeah, there's a lot of opprotunity when using tags in that fashion! Especially when it comes to the technical aspect, you can make a ton of different features work by simple adding a (hidden) tag to a thread
more examples:
"convert" a forum thread into a news post by simply adding a hidden tag to it
Tag categories could technically just be another tag on a thread (woot normalization!), global posts just have every tag (woot denormalization!), etc, etc
Ditto w/ private threads, just tag them with a username (v2, heh)
any sort of adding "statuses" to threads for whatever use you can think of - just add a (hidden) tag!
