Lots of times after I "preview" I just forget that you have to hit "continue" again to actually post. My preview looks good and I think I'm done so I click on one of the menus at the top without even thinking about it.
If you actually got the "post" screen and the redirect message, it might have just been a software hiccup. This board seems pretty immune to those but you never know. On boards where that happens a lot, I've gotten into the habit of selecting and copying my message before hitting the post button in case something goes screwy. If the board is messed up I can paste it into a text document and save it to try to repost later on.
I can feel your frustration though, because it still does happen to me... I prepare a VERY long post and then forget to copy and then lose it, and you don't even want to go and retype it, it is almost more frustrating trying to remember what you said than creating it in the first place.
