+<h3><a name="posinclass">Locating commodities in the YPP client UI</a></h3>
+
+In the Voyage Trading Plan, YARRG indicates after the commodity name
+where in the YPP commodity UI each commodity can be found. This is
+done by showing one of the following indications in the table:
+<blockquote>
+ TT, T, M, B, BB
+</blockquote>
+indicating whether the commodity is in the top, 2nd, middle,
+2nd-to-last or bottom fifth of the list of commodities of the same
+class, respectively. For example,
+<blockquote>
+<table><tr>
+<td>Fine pink cloth
+<td><div class=mouseover
+ title="Fine pink cloth is under Cloth, commodity 14 of 55">T</div>
+</table>
+</blockquote>
+indicates that Fine pink cloth can be found under Cloth,
+between 20% and 40% of the way down through the types of Cloth.
+If you mouseover that in a suitably equipped browser you should see the
+text:
+<blockquote>
+Fine pink cloth is under Cloth, commodity 14 of 55
+</blockquote>
+<p>
+
+Note that not all commodities are categorised, and that the exact
+location of the commodity may vary because the system only considers
+the list of all possible commodities, not the list of actual offers at
+the island in question.
