I recently noticed that we have a total-party-kill tag. It seems reasonably useful, if only to link together a bunch of related questions, but it's currently only used on three questions (and I added it to one of those).
A few highly voted questions that perhaps could use this tag, but currently don't, include:
- My PCs have a plan that will get them all killed; how and why should I save them?
- How can I prevent a TPK without obvious Deus Ex Machina?
- How can I plan a TPK finale that doesn't look planned?
- Game Over in RPGs?
- How can I dissuade my players from attacking a deadly foe who isn't meant to be attacked?
Should I add this tag to more questions, to make it actually useful for searching, or should I remove it from the few questions that have it? And if the former, should tpk (which currently does not exist) be made a synonym for it?
OK, looks like we have a fairly clear consensus that the tag should stay. I've marked nitsua60's answer as accepted (since I can't pick more than one), and I've added the tag to the first four questions listed above, so that they can be found when searching for it. From there on, it should be fine to let it grow organically.
