Adding email to sharing content plugin

Jordan,
Sorry for the delayed response to this. Email sharing is something we've gone back and forth on adding. The problem with it is abuse. If you let users type arbitrary emails, and (oh my) a message, it will immediately be automated and used to send spam from your site. It's not pretty what happens to email contact forms.

That's really not an alley we've wanted to go down because, while the initial implementation is easy, the added work of trying to lock it down to just guests, or limits per day / IP, or some other mechanism quickly makes it too much work in the long run.

It's something we've thought about before though, and maybe you can convince us more on how awesome it would be, but it's simply not something we've had requests a lot for and is something that would keep us up at night if we decided to do

I hope that makes sense, but as always, your feedback is welcome.

Thanks,
Alex
