When you click on a user's name to send him or her an
email, a default subject line should be included. The
email could contain a standardized string which would
help with mail sorting.
Possible default subject headers might be:
[AGoT game "A Storm of Swords"]
[AGoT game "A Storm of Swords"] [Lannister]
The format for mailto link is as follows:
<A HREF="mailto:user@domain.com?subject=Message%20Title">
Click to send mail</A>
In order to include " marks in your message subject,
you may need to HTML escape them. A developer's
reference for the mailto tag is available at this address:
