| 5 | -Description: No more SPAM by spiders scanning you site for email adresses. With CryptX you can hide all your email adresses, with and without a mailto-link, by converting them using javascript or UNICODE. Although you can choose to add a mailto-link to all unlinked email adresses with only one klick at the settings. That's great, isn't it? | |

| 5 | +Description: No more SPAM by spiders scanning you site for email adresses. With CryptX you can hide all your email adresses, with and without a mailto-link, by converting them using javascript or UNICODE. Although you can choose to add a mailto-link to all unlinked email adresses with only one klick at the settings. That's great, isn't it? | |
