In this example, we're going to see what happens when a proposal
drifts away from the latest Radicle identity.

First off, we will create two proposals -- we can imagine two
delegates creating proposals concurrently.

```
$ rad id edit --title "Add Alice" --description "Add Alice as a delegate" --delegates did:key:z6MkedTZGJGqgQ2py2b8kGecfxdt2yRdHWF6JpaZC47fovFn --no-confirm
✓ Identity proposal '6b73fce909f612d5d92084b91309d73c21fea396' created
title: Add Alice

Now, if the first proposal was accepted and committed before the
second proposal, then the identity would be out of date. So let's run
through that and see what happens.

```
$ rad id accept 6b73fce909f612d5d92084b91309d73c21fea396 --no-confirm

Now, when we go to accept the second proposal:

```

Note that a warning was emitted:

If we attempt to commit this revision, the command will fail:

So, let's fix this by running a rebase on the proposal's revision:

Finally, we can accept and commit this proposal, creating the final
state of our new Radicle identity:

$ rad id show 2bf3a85e209d10b11a65e7ed8a8085f6f18ac6bf --revisions
