Template:Email
From Oregon Hikers Field Guide
Somewhat obsolete! This template used to be needed to simplify the inclusion of email links in wiki pages. Now you can simply use an attribute of Type:Email such as the email attribute, e.g.
[[email:[email protected]]]
On pages that belong to a person, organisation, or similar "agent", you should use Template:Mailbox to get additional FOAF annotation in one step.
If you prefer using a template over an attribute, just write
{{email|[email protected]}}
Doing so creates a semantic annotation for the email, so that you can actually search for emails later on.
