Hopefully, you made note of his email before the moderator removed it. Email addresses are not allowed to be posted on this site in order to prevent spam. Once a member has made 3 posts, the personal message system can be used to contact others so that confidential info can be sent, such as emails, phone #. In order to use the PM system, you click on the little green scroll under the user name.
If you do need help with using the PM, post a request here and someone will work you through it.
William has only made 1 post so you won't be able to contact him through the PM.
