I wanted to delete this post in this section but could not. So, cross posted in correct section.
You're right: you cannot delete your posts. Editing them, however, is trivial and involves clicking on the button marked 'Edit' and modifying the text you wrote.
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.
