Google Apps Email Alias - video by Goldy Arora - http://www.goldyarora.com
Sometimes you need to create multiple email addresses either for yourself or for your team such as sales at your domain.com, but each new email id comes with a license cost from Google.
In this video, i will show a way to create multiple additional email addresses without paying to Google, via creating nick names (or some call it alias email ids)
You should be able to also send emails from these nick name email ids with Gmail's "Send Mail As" feature
