Despite repairs to the site, I know there is still a double/triple posting issue, so to help you avoid the problem in the meantime: After you have hit the post reply button, if the leave/stay on this page message appears, click leave, do not attempt to repost. Alternatively just open another tab then close the current tab, again requesting to leave. This suggestion should avoid double posting. Basically if you see the leave message, your post should have already been submitted. There are some instances where the post has not appeared immediately on refreshing the page, in that instance check again a few minutes later. If you have posted a lengthy post or thread, you could copy it in to word as a back up. Obviously the site owner is continuing to resolve the cause of this issue. Thanks brb
