Email addresses in "Contact Administrators Link" should be encrypted by default

The only publicly accessible part of my wiki is the "Contact Administrators" page. These emails aren't encrypted, and even if they are "masked" they are very easy to read by spambots. Stronger encryption, such as available at http://automaticlabs.com/products/enkoderform/ would be a great benefit. I don't mind logged in users seeing my plain-text email, but I'd like to be able to configure the public page differently. Thanks for your work.,
