Nice, thanks Michele.
How effective do people find these measures?
Is it a battle worth fighting?
Should the email address be printed on the site plainly for people to make a note of, or copy and paste...?
Do people use coding measures to print them out... is that worth it?
Etc etc...

Seriously though, very curious. I usually just put the email up there plain old fashioned seeing as you're going to be fighting spam at various levels elsewhere anyhoo...
