    The rule-based subscription module is for advanced users, and allows you to use filters to specify which events you are interested in hearing about.

  <p i18n:msg="">
    Every rule is in the form of:
    <div class="syntax">
      <span class="realm">realm</span>, <span class="category">category</span>: <span class="rule">query rule</span>
    </div>
  </p>
  <div py:for="rulenum, rule in enumerate(rules)" style="padding: 0.5em">
      <input type="hidden" name="rule_${rulenum}_id" value="${rule['id']}" />
      <input type="checkbox" name="rule_${rulenum}_enabled" checked="${rule['enabled']}" value="1" />
      <select name="rule_${rulenum}_category">
        <optgroup label="${realm.capitalize()}" py:for="realm in categories">
