cannot find ---- Click on "Thread Tools" link above first post in the thread and select "Delete Thread".
The feature hasn't been removed. The issue is that it's only visible within 60 minutes of starting a thread.
You can't. Hopefully Baron will rectify that, because I cannot imagine the harm of someone deleting their own thread after more that 60 mins. I mean, give them 24 hours. WTF. He might be thinking longer term...Like, you should not be allowed to delete a thread you created that is 5 years old, because of all the wisdom that attached itself to it, like barnacles.
The constraint is there to prevent people from making trading calls and then going back later on and editing the direction of their call if things go against them. It's also there to prevent someone from starting a popular thread with a lot of replies and then deciding days later to delete the whole thread.
