   Format: MarkdownItexYet another unhelpful error message! It appears to be to do with the stickiness of the discussion - I could edit older discussions, and couldn't find another one that I couldn't edit other than that one. Making it unsticky then made it work. So I've made it unsticky for the time being, let me know when you're done editing it and I'll make it sticky again (unless you have permission to make it sticky yourself, I don't recall if you do or not). (Needless to say, I didn't _actually_ edit any of the discussions that I tested; I just checked to see if I got the same error message or got the edit box.)

   Format: MarkdownItexH'm, I thought about stickiness when it came to the original post, but it never occurred to me that the comments would be sticky too! After all, I added those comments *after* the post was sticky, right? (H'm, maybe not, I don't remember.)
