There are a couple of different ways to manage how people can access your hives hub. But no matter which way you choose, you can rely on the fact that it will always be easy for them to join.
Direct link to your hives hub
With this way you'll be able to share a link that brings people direct to your place. And they will be able to sign up with email (magic link), google, microsoft, or slack.
Invite with email
If you want to invite specific people through email, this is the easiest way to do it. The people you invite will then get an email with a link that brings them straight to your page in hives.
Share a link to a specific collection
When you have a specific collection you'd like to share with people, you can easily do that by activating the "Share to web" feature on your collection.
