I started to use AngularJs and I really love it, and just discoverd this pluging for angular -> https://github.com/witoldsz/angular-http-auth, that lets you implement a identification system.
Anyone know a resource like the one I mentioned for easy send emails ?
You'll have to implement sending emails on your server. Alternatively, there are some paid services like Postmark that give you a JSON API that would be easy to hook into AngularJS to send emails.
