I've updated the Novam (http://mappa-mercia.org/novam) today. The main new feature is the search box which allows you to conveniently locate your area on the map. When I discovered Nominatim (http://nominatim.openstreetmap.de/) last week, I was intrigued by it and decided immediately to add support for it to Novam.

Other changes in the new Novam version are:

* OSM node id and version of each bus stop is now displayed.
* A link to the OSM node history has been added to the stop viewer.
* The permalink now also includes the currently selected stop.

After I spent yesterday evening with referencing postboxes in my area (http://www.dracos.co.uk/play/locating-postboxes) I realised that there were still a lot missing. Then, a bit later that evening I had an idea: Postbox orienteering.
So, today I printed a map of the area and marked the approximate position of all the postboxes which I could not find yesterday evening. Then I set out for my postbox orienteering run. Whenever I found one of the postboxes I marked their exact location the map and jotted down the reference code.
12km later I had 12 new postboxes and finished a very nice run.
