stop the bastards!

most of you i'm sure are aware of the recent spate of spam comments on our blogs, & i've come across a way to stop them - if you log on to blogger, go to 'settings', then 'comments', & there'll be an option to add word verification for comments. change this to 'yes' & if anybody wants to add a comment, they'll see one of those swirly jumbled letter things & will have to copy the letters to verify you're a real person & not a computer programme. (if you're not sure what i mean, go to my blog & try to add a comment)
