       <h3><a name="CommitterAgreements"></a>Committer Agreements</h3>
+      <p>For Eclipse projects (and the open source world in general), <em>committers</em> are the ones who hold the keys. 
+      Committers decide what code goes into the code base, they decide how a project builds, and they ultimately 
+      decide what gets delivered to the adopter community. Committer status is assigned following a demonstration
+      of merit (generally a record of high-quality contribution to a project) and a successful 
+      <a href="/projects/handbook#elections-committer">committer election</a>.</p>
+      <p>Committer status is assigned on a project-by-project basis. That is, individuals have committer rights only 
+      on those projects for which they hold committer status. For all other projects, they are contributors.</p>
+      <p>Our committer provisioning process is automated: new committers will&mdash;following their successful
+      election&mdash;be contacted by email to engage in our <em>agreement workflow</em> (also referred to as our
+      <a href="https://www.eclipse.org/projects/handbook/#paperwork">paperwork process</a>), which guides
+      them through signing those agreements that they need. The agreements are provided below for convenience.</p>
       <ul>
         <li><A href="committer_process/EclipseMemberCommitterAgreementFinal.pdf">Member Committer and Contributor Agreement:</A>
-          This agreement is used by Member companies to cover all of their committers participating in Eclipse projects.
+          The Member Committer and Contributor Agreement (MCCA) is used by organizations that are members of the 
+          Eclipse Foundation to cover all of their employees who participate in Eclipse Foundation projects as committers. 
         </li>
         <li><A href="committer_process/EclipseIndividualCommitterAgreementFinal.pdf">Individual Committer Agreement:</A>
           This agreement is used by committers participating in Eclipse projects who are not covered by a Member
           Committer Agreement.

-        <h4>2019 Re-sign Exercise</h4>
-        <p>The Eclipse Foundation has updated its standard contributor and
-            committer agreements, and all our committers and contributors, as well
-            as those members who have member committer agreements, will need to
-            re-sign their agreement with us.
