I've noticed that there is a word filter (which must be from the stone age or so), I almost stumbled about the same: writing "smart" and "watch" in one word, thus 4 letters in the middle of the combined word were blank. Luckily I was fast enough to edit my post.

I remember that you wrote it the same way. Maybe your post was automatically removed, because it contained a filtered word. At least a possible explanation.
