Why can't I edit or delete my posts?

[Marconi]

I wish to delete a post I made and I cannot find the option. Can you help?

Funny your post shows that it has been edited, so did you figure it out?

When I made the post I did not think about being in the Swap section. That is where I noticed that I could not delete or edit my post. I guess there is a rule to prevent changing terms, but what if you wanted to change a mistake made in hast?
