Is anyone being kept from posting by one of those "Prove you're not a robot" type signs? In this case, instead of simply clicking on that, you're shown a big block of photos, and told to identify them (?), and the bottom line is, no matter what I do I'm not able to post when it comes up. (I've seen it elsewhere, but mainly on this site.)
There's a weird sort of Murphy's Law in my case. It only seems to happen when I've typed something two or more paragraphs long, instead of anything very short. As if it's just waiting to happen when you've put a little bit of effort into it.
