+      <strong>Nomination Pools are evolving!</strong>
+      <br />
+      <br />
+      Soon you will be able to participate in a pool and in OpenGov with your pooled funds, and switch pools with the same ease as solo stakers!
+      <br />
+      <br />
+      You do not need to do anything, unless you are participating in a pool and also staking solo from the same account.
+      <br />
+      In this case, you need to unbond the funds you are staking solo <strong>as soon as possible</strong>, in order to avail yourself from the automatic migration that will happen, and avoid migrating your pool membership manually.
