Template:Mailto
This template simplifies the addition of clickable email addresses to a page. It takes one or two parameters, as follows:
- The first parameter is the email address.  It's the only required parameter.  If no domain is given, the domain is assumed to be "cs.jhu.edu".
{{mailto|support}}→ support@cs.jhu.edu
 - If you give a domain, the entire address will be used as-is.
{{mailto|postmaster@jhu.edu}}→ postmaster@jhu.edu
 - The optional second parameter gives alternate text to display instead of the email address.
{{mailto|support|CS IT Support}}→ CS IT Support
 - For completeness of the examples (and for testing the template), if the first parameter is omitted, an error is displayed.
