Very odd.
No posts were moved or deleted that I could find - nor was there a database hiccup which could have prevented them from reaching the forums.
A few times when posting a new thread I have used the preview option, adjusted stuff, previewed again and evidently after hitting preview a few times mistook it for the submit button - which is a real bummer if you've spent time pennign a longer post.
Apologies at any rate for whatever happened - I'll keep my eyes peeled just the same.
What topic/forum would it have been headed to?
