Could an option on the "Email the Classmates" be added to manually enter an email address.

The purpose would be to respond to requests from non-members coming through the Contact Us page without revealing admin addresses by using an email client.

Passing the suggestion on to Brad.

I can't go into significant detail here but it makes spamming too easy. And believe me when I tell you people spam. Every day many thousands of spam emails are sent into our system, 99.9% of which we're able to auto detect and weed out. I also suspect most Admins wouldn't find the option under Email The Class since technically we'd be adding the ability to email somebody other than the class there.

A good alternative though is just open a free Gmail or hotmail email account for situations like this. Takes 5 minutes and you've got your anonymity. Or buy an email box at your domain name which is relatively inexpensive.
