Is there a way to share a pump.io post by emailing it to someone? Maybe as a shortened URL as the Twitter provides?
If it's a public post you could just email the URL?
I guess yes, I could email the URL. but my thought is, why not make that (email link) an option when using the [share] button?
Email link how? There are lots of ways in which people use e-mail. Supporting those would be incredibly complex.
Copy-pasting the post URL wherever you wish is simple enough, don't you think?
