+    Configuring jabber account
+  <p>
+    A jabber account is used by git-annex to communicate changes between #
+    repositories. It can also be used to pair up with a friend's repository, #
+    if you want to. It's fine to reuse an existing account; git-annex won't #
+    post any messages to it.

+    <i .icon-info-sign></I> If you have a Gmail account, you can use #
+    Google Talk. Just enter your full Gmail address (<tt>you@gmail.com</tt>) #
+    and password below.
