Is there a "modify?"

I can't seem to find it. I hope it's here, it's so useful.
Has anybody found it?

you mean edit your posts

there is an EDIT button on the lower right corner of the post

Also at the top of the window there is a button labeled 'user cp'. Try it.

Oh, Edit. How dumb of me. I was so busy looking for 'modify'
I didn't even think of 'edit.' Thanks a lot.
