+<title>Usertags</title>
+<para>
+You may wish to use BTS usertags when submitting bugs across a number of
+packages. Usertags are similar to normal tags such as 'patch' and 'wishlist'
+but differ in that they are user-defined and occupy a namespace that is
+unique to a particular user. This allows multiple sets of developers to
+'usertag' the same bug in different ways without conflicting.

+<para>
+To add usertags when filing bugs, specify the <literal>User</literal> and
+<literal>Usertags</literal> pseudo-headers:

+<screen>
+To: submit@bugs.debian.org
+Subject: <replaceable>title-of-bug</replaceable>

+Package: <replaceable>pkgname</replaceable>
+<replaceable>[ ... ]</replaceable>
+User: <replaceable>email-addr</replaceable>
+Usertags: <replaceable>tag-name [ tag-name ... ]</replaceable>
+
+<replaceable>description-of-bug ...</replaceable>
+</screen>
+<para>
+Note that tags are seperated by spaces and cannot contain underscores. If you
+are filing bugs for a particular group or team it is recommended that you
+set the <literal>User</literal> to an appropriate mailing list after describing
+your intention there.
