anti-spam new member login?

[Nathan Ross]

I've lowered the threshold today by a third to see if that helps. Apart from that, every new member has to answer both a Captcha (the letters-numbers gobbledygook) and a Security question related to the Roman army.

Thanks! I didn't know that - it's been a while since I registered...

Hard to see what else might be done then... although a more difficult question might work! As I once suggested to Robert, 'what was the colour of the Roman army tunic?' ought to sort the wheat from the chaff...
