It's common that in projects where there are already multiple
delegates that one of those delegates meets someone that they want to
bring into the project. So let's see how Alice and Bob end up inviting
Eve to the project.

First, we'll start off with Alice adding Bob. It's necessary for Bob
to have a fork of the project and Alice must be aware of the fork:

``` ~bob
$ rad clone rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --scope followed
✓ Seeding policy updated for rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji with scope 'followed'

✓ Creating checkout in ./heartwood..
✓ Remote alice@z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi added
✓ Remote-tracking branch alice@z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi/master created for z6MknSL…StBU8Vi
✓ Repository successfully cloned under [..]/heartwood/

Run `cd ./heartwood` to go to the project directory.
$ cd ./heartwood
$ git push rad master
```

At this point Alice can follow Bob, fetch his fork, and add him to the delegate
set:

``` ~alice
$ rad follow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk --alias bob

✓ Nothing to announce, already in sync with network (see `rad sync status`)

✓ Fetched repository from 2 seed(s)

```

Bob can confirm that he was made a delegate by fetching the update:

``` ~bob

✓ Fetching rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji from z6MkvVv…Z1Ct4tD..
✓ Fetching rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji from z6MkuPZ…xEuaPUp..

$ rad inspect --delegates
did:key:z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi (alice)
did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk (bob)
```

Later, Bob meets Eve at a conference and she wants to take part in the
project. For Bob to propose Eve, similar steps need to happen as
between Alice and Bob. Eve first needs to setup a fork:

``` ~eve
$ rad clone rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --scope followed
✓ Seeding policy updated for rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji with scope 'followed'

$ git push rad master
```

Bob then follows Eve and fetches her fork and adds her as a delegate:

``` ~bob
$ rad follow did:key:z6Mkux1aUQD2voWWukVb5nNUR7thrHveQG4pDQua8nVhib7Z --alias eve
✓ Follow policy updated for z6Mkux1aUQD2voWWukVb5nNUR7thrHveQG4pDQua8nVhib7Z (eve)

$ rad id update --repo rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --title "Add Eve" --description "" --delegate did:key:z6Mkux1aUQD2voWWukVb5nNUR7thrHveQG4pDQua8nVhib7Z --no-confirm -q

✓ Fetched repository from 2 seed(s)
✓ Synced with 2 node(s)
```

Since the `threshold` is set to `2` it's necessary for Alice to also
accept this change:

``` ~alice
$ rad sync
✓ Fetching rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji from z6MkvVv…Z1Ct4tD..

✓ Nothing to announce, already in sync with network (see `rad sync status`)

```

At this point Alice will want to fetch so that she can get Eve's fork:

``` ~alice
$ rad sync --timeout 3

```

Note that `z6MkvVv69U1HGuN6yUd8RiYE8py6QYRzuQoG45xSpZ1Ct4tD` fails to
fetch since it did not have Eve's fork, and similarly, it could not
fetch from Alice and times out for the same reason. However, Alice was
able to successfully fetch from `z6MkvVv…Z1Ct4tD`, since it did have
Eve's fork.

Since the network is eventually consistent, if Eve decides to `sync`
(this could also happen through a transient announcement), then we can
see that both seeds are `synced`:

``` ~eve
$ rad sync
✓ Fetching rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji from z6MkvVv…Z1Ct4tD..
