Any way to edit original posts?

Wondering if there’s a way to edit old posts for topics you’ve started. I wanted to add links to the most current version of my game to the OP for my feedback topic and fix the picture which broke.

There’s a configuration available to admins (post edit time limit) governing this that defaults to 2 months. So there are three ways to do what you want: 1) admins changing this value, 2) post marked as wiki (can’t use retroactively unless admin can change the type of an existing post), 3) plugin adding per-user limits.
