What Sass Mixins come included with NationBuilder?

How do I see the style entries that make up the mixins without applying them to my theme? For instance, how do I know what a fancy-button looks like?

Official response from Lilia Villa

SASS is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance and more.  

Mixins are one of the most powerful Sass features. They allow re-use of styles – properties or even selectors – without having to copy and paste them or move them into a non-semantic class.

The mixins used in NationBuilder themes (gradient, border radius, box-sizing) come from Compass. You can learn more about them here: http://compass-style.org

'Fancy Buttons' is the only non-Compass mixin that has been added to NationBuilder. All the submit buttons use them by default. You can learn more about them here: http://brandonmathis.com/projects/fancy-buttons/

To use your own mixins in place of existing ones, you can just remove the @import and customize your own styles.

What is the difference between Broadcasters, Supporters, Prospects, and Non-Supporters?

Official response from Lilia Villa

Broadcasters:  the voices of your nation. They can be your organization, yourself, your staff, or anyone else you want interacting with your supporters. You can set up multiple broadcasters and the communications of each broadcaster are managed and tracked from their individual dashboards under the Messages tab. Broadcasters are different than the people in your database, and they do not have person records. You can allow all people with control panel level permissions to access and communicate as a broadcaster, or limit them to only a single person. All outgoing communications from your nation go through a broadcaster. They can send email and text blasts, and can receive text messages and voicemails.

This video from NationBuilder Live walks you through the communication features associated with a broadcaster:

The "Communications and broadcasters" video is also available in high definition on our YouTube channel.

Primary Broadcaster: When you go to Websites > [Website Name] > Site settings, you will see a place there for specifying a broadcaster.  That determines what Facebook page, Twitter account, and who the main email auto-responses in your nation come from. The broadcaster chosen must have an email account associated with it. 

Supporters: your nation’s advocates and opt-ins for messaging. People are automatically added as a supporter when they subscribe to your email updates, follow you on Twitter, donate/volunteer on the website, or choose to receive text messages. Twitter followers are included because you are able to use direct message functionality to start one-to-one communication with them.  

Prospects: people you have to convince before you can gain their support and convert them into advocates and opt-ins. In a political campaign, prospects would be your potential voters. Be exceedingly careful in contacting prospects via any kind mass email - here are some tips for conducting outreach without spamming.

Non-Supporters: people who do not want to receive emails from you and haven’t taken any action. They are in your database because they have unsubscribed, have liked one of your Facebook posts or have tweeted about you but are not following you.
