List of towns is taken from here:

  http://gagravarr.org/cgi-bin/where_am_i.py

So basically it comes from OSM data, with a slight delay (few weeks maybe) to 
see new towns appear depending on when nick and I update our websites.

To make the almien website check the gagravarr website for new towns in an 
area, there's a tool at:

  http://almien.co.uk/OSM/Places/?action=import_places

Most people don't need to use that though and it will eventually be automated 
- just keep tagging your citites with place=city, place=town, place=village 
as normal and they will eventually show-up on the site.

(See wiki entry [[OSM at home]] for more things you can do to help, such as 
tagging cities with their wikipedia page names, or categorising cities)


Regarding size, it's currently fixed at a certain number of degrees.  It will 
soon be variable depending on whether the place is a city, town, villlage, 
hamlet, etc.  I need some idea of what numbers to use though (how many 
degrees wide a city map should be)

Map size probably shouldn't come directly from OSM data (no "city_size=0.4") 
because some joker could set the value to be abnormally large or small, 
messing-up our data-transfer systems and crashing the computers of people who 
try to render the result.
