[Web4lib] anti-spam email adress

[Brian Sheppard]

Pierre,
As already mentioned, you can encode the entire value of the href as  
a numeric entities. This is probably a feeble measure these days, but  
when I implemented in a few years back, it made a noticeable  
difference. We explicity chose to avoid javascript or rendered image  
solutions for accessibility reasons.

It's probably safest to just send the user to a submission form that  
works with a simple cgi, though that can be off-putting to users.
