The ultra observant will notice a missing email address.
Where addresses for people who are helping in various providers are published we do remove them, if the email address is not meant to be a publically visible one. The problem being people move around departments, and there is a tendency for people to bombard with irrelevant or time wasting issues.
If this causes a problem for someone, i.e. they wanted to find out something specific then feel free to pester me, and I will then pester the appropriate people. This system works as I often know where the answer is, and/or can spot patterns in requests.
