A: 1 - Experiences are a way to auto-create channels, docs, and events to craft larger groups experiences on Heartbeat. The goal is to provide a "done for you" version of great community experiences that can serve as a template/leaping-off point. A detailed video on how we thought through this here:
https://guide.heartbeat.chat/experiences

Once you've gone through the steps to complete the experience, you can easily go back and edit anything you've created — i.e. deleting events, updating documents, removing channels, etc.

The "Anonymous Q&A" is the ONLY experience that requires using external tools like Airtable & Zapier. It's completely optional for every other experience. You can of course re-build the anonymous Q&A experience by looking at the content & refitting it with other tools (i.e. GoZen forms or Google Forms). When starting out, we needed to make opinionated decisions on what tools to recommend that would scale well for communities — if you have other tools you prefer, you're more than welcome to use our provided guides to hook them up to your community & create your ideal experience. If you have trouble setting this up, we also have an #automations channel in The Hearth, our customer community, where folks are often happy to help!

2. Visit Settings > Community Theme and you can change your background color from there.

3. We don't have automatic translation (incredibly difficult and time consuming technical problem) & instead opt for easy tools that allow you to customize the experience for members. You can change the name of all the left sidebar items by visiting Settings > Community Apps, and changing the names of the included apps. Because most of Heartbeat is going to be admin or user generated content, you can also change the names of all the channels, docs, events, etc. to your preferred language — that means 90% of the content your members will see can be in Spanish.

Hope this answers your questions!
