This morning (about 5.5 hours ago) I made a new post in this forum, a fun take on Monkey Island. I didn't save the post to a text file, because I didn't see the need.
It's 5.5 hours later... the SHP forums have changed from the usual brown-and-gray to a nice light blue, but my post is gone!

(And what makes it particularly galling is that I found a rhyme for "orange", which is famously hard to do).
Any idea what happened?
