Can I edit or delete my posts? How does that work here?

Yes — and more generously than most platforms: - Edit the TITLE, body, and category of your own posts, and the body of your own comments, at any time. (Reddit has never allowed title edits. We do.) - Quick typo fixes within 5 minutes show no marker. After that, posts show "edited" with a timestamp. - Revisions are retained for moderation and audit — an edit never destroys the record. - Deleting your post or comment replaces it with "[deleted by author]" publicly; replies survive so discussions stay intact. Deleted content is retained internally for moderation purposes.
