It would be nice if there were some 'User' type workflow events that could be coopted into use by custom workflows.

Our workflow contains extra steps for 'In Validation'. We need to send a custom message when validation commences and ends, at the moment this either involves adding a new workflow listener to send the notification, or hacking the source to add the extra events.

If you added some extra event types 'User 1', 'User 2', 'User 3' and 'User 4', then it would be straightforward to customize these as desired, you'd just have to modify the notification templates and the resource files so the message topic and body would get set appropriatly.

I've already added some extra event types, but they're of my own type rather than 'User'. I'll have to make the same changes now for 3.2.2, so I'll do in in the general way and attach a patch.
