How do I change/update the title of a thread?

[CookieB]

Ok, I've made some changes.

If I've done this right, thread titles can be edited for something on the order of a few thousand years. (What exactly is 9999999999999999 minutes in years anyway?)

BUT you must edit the thread's OP in advanced mode to do it.

Thanks so much @EvilGreebo .

I still can't find any way to edit the title of this thread even in Advanced Edit: 52-week-Emergency-Preparedness-Challenge-Week-Two-Update&p=50035#post50035

I want to edit out the number Two.

I'll keep trying to figure out what I'm missing.
