Wait, wait, this is a programming question! I want to build an extension if none exists.
Imagine this: you come across a webpage that says "Just send a message to
[email protected]" but to actually send the email, you need to highlight the address and then cut and paste it into the recipient field of a new compose window of your email client of choice.
Obviously life would be easier if it were simply a mailto: link, so you could click on it and have a new message created automatically. (Or if the page designer had used a form, perhaps ...)
I was originally going to ask if there was an extension to enable similar functionality for unlinked twitter @username mentions but I thought this email address problem would be a simpler situation. If you think it would be useless, perhaps I should look at the twitter username problem instead.
Thanks for your feedback.
