Typing it in a text editor does for the spelling etc, but you can check that with hot lingo or something like that anyway . The really handy thing with a preview is that it is such a handy way of checking that any links work ok - as I have just done now. (And if I hadn't checked it would have come out wrong, because I had missed something out.)

No urgency about it, but I thought I'd put it up here for the future.
