We have a lot of dictionaries available on addons.mozilla.org and BlueGriffon can use them. So if you could just add the following to your dictionary's install.rdf, that would help BlueGriffon users a lot:

<em:targetApplication>
<Description>
  <!-- BlueGriffon -->
    <em:id>bluegriffon@disruptive-innovations.com</em:id>
    <em:minVersion>0.8</em:minVersion>
    <em:maxVersion>1.0</em:maxVersion>
  </Description>
</em:targetApplication>
