Anybody know how to delete post/threads?

I’m kinda new to this and have no idea how to delete posts or threads on my mobile device ! If you know please let me know !!!

The general rule around here is

"you post it, you own it."

And it's really funny watching some people back away from it

And the moral of this story is.......

Don’t write anything that you do not want available to infinity and beyond.

Its pathetic when something like this is requested and ownership basically gives you the finger and no help! They have the ability to edit it move it or completely delete it!
It gets done all the time for what ever reasoning .
