Oops

When you're working under pressure, it's important to remember to double check everything you've prepared -- captions in particular. With my work at www.bitweb.tv, I've been caught out a couple of times, making simple mistakes...a missed-out letter or space, for instance.
The time it happens most frequently is where you're putting up what the BBC used to call a "tum-tab" (so-called because the name of the person appeared across their tummy). If you're using quite a small point type, something like this can go unnoticed in the rush. You publish to the web and, if you're lucky, you yourself notice and change it; if you're unlucky, then the person him/herself sees it and doesn't like it.
So check, check and double-double check. On such simple things are jobs lost!
