The last edit there was about a year ago, and done by a Moderator, not the user. Especially for the scripting section it's vital not to allow editing to prevent people from wiping what may be useful for others, after they have gotten their solution. For reasons like this, you can only get it edited if you report the post and let us know (n the report reason) what it has to be changed into, after which one of the moderators will do it for you as soon as possible.
