So is your javascript method breaking up the email so its not together in the source? If so, thats a good idea. I've been trying to think of a way to have links like that that doesn't have the email or contact info in the source.

Because I haven't wanted spam and haven't thought of a good way to stop it, I just use a contact form, and on that just have a simple question that verifies if its a human or bot. Not super super effective, but I usually don't have a huge spam problem.

EDIT: In PHP, could you break it up by just exploding it after a certain number of characters? Or does it have to be after a character has appeared.
