I think you should be able to delete a post within the initial edit time, 10 minutes is it? Especially in the I.D forum where someone usually beats you to the answer by a few seconds, and you then have to edit your post by saying "well done" or something else pointless.
And perhaps the option to just close/lock your own thread would be good, to prevent people bumping it when for all intents and purposes it is finished. Any chance? :wave2:
