+---++ Generation of the twisty ID
+
+When you define the =id= parameter a twisty the actual ID is appended by a number that counts from 1 for each twisty to ensure that the ID is unique.
+
+If you do not define an =id=, the plugin autogenerates an ID based on web and topic names and a counter that counts from 1 for each twisty.

+In ajax application you may need to ensure that the ID is unique for each call. For this always define the id parameter in your application to ensure a unique id for each call.
