Stray posts are very often moved into official threads, so that Moderators and Developers can see trends with problems and suggestions, and gather feedback more readily. Also to enable better functioning of the forum search tool, for the benefit of all members.
If your post has been moved, it's still quite easy to find it again.
- Click on your username at the top right of the page; this brings you to your profile page.
- Click the 'statistics' tab, then 'find all posts by..' and all the posts you've made will appear.
- Then simply click the link to the post you're looking for, and you'll be taken to the thread.
Note that the first post of the official thread is where updates and further information can be found, so it's very much worth reading that one, as well as any responses to your post.
