Can't delete my old posts.

Hello, I can't figure out a way to delete my old posts. It's not that I want to spam, but I figured out a better way to word my posts and bump them. I don't want to be seen as someone whose profile is full of the same thing, I'd rather just bump it tbh. How can I delete a post of mine? All help is appreciated c:

If your post is the first in a thread you cannot delete it. That's to prevent a member from ebbing able to delete an entire thread with many responses by removing their post.
