I encountered some nasty forms on the British Gas site recently. I couldn't remember my password, so tried to reset it. The forms use some pretty but ultimately useless AJAX tooltips that don't actually advise you on what validation is being applied to the fields, and what help is available becomes unavailable if you shift focus; to another form field or browser tab, for example.
What's worse, one of the password validation criteria -- that you can't choose one of your last 12 passwords -- isn't listed *anywhere*! I only found this out by emailing BG.
Luckily, I remembered my password and didn't need to reset it after all.
