Deleting posts in the campaign forum

I have been running a campaign for some time now, but have found that their are a lot of posts in the campaign forum that are no longer needed, but can't seem to find an option to delete them; if someone knows about this and can help I would appreciate it.

Hi Sean. The GM of the game, or the author of any individual post in the campaign forum, can press Delete on a post. The Delete button appears in the line of button-links under your name, on your post. &nbsp;If the GM or post-author deletes the first post in the thread, this will hide the thread. Important note, the post's text / contents will still appear visible to the GM, but there will be a small colorful message saying "This post has been deleted by the author or a moderator" and in this form, the post will not appear to the other Players in the game, only to the GM.

Thank you, that makes it much easier.
