Non repetitive element in a list

Hi there. I have a team member list and would like to add the e-mail with an onclick event per member (to solve the spam problem). The problem is that I can’t add a non repetitive element to a list member. But I do need one for the onclick event don’t I?
This is the site: Intersys – Unser Team aus Spezialisten mit Persönlichkeit In the upper section (Sales and Marketing) I added a text field below the list element. That only works while I do not have more members than one line. That why in “Software Experten” it doesn’t work.
Has anybody an idea how to solve this problem?
Thanks a lot!
Cheers, Patrizia
