I found this in the help section
Modifying or Deleting a Post
To modify a post, click the Modify button and make your changes. Note that most forums are likely to be configured to show the date and time of the last edit, but the administrator(s) may also allow a short period to elapse before this happens.
To delete a post, click the Delete button followed by OK from the Remove this message? box that appears. Some forums may also allow you to remove topics or polls that you start, but the buttons for these are usually at the bottom of the page.
OK what I'm I missing here? I would like to edit my Kart Ad but can't find the "Modify button" where are you hiding it at?
Thanks, Randy
