Don't stick to the documentation on the wiki too hard, especially when 
it comes to numbers (city always more than 100.000 inhabitants) or set 
characteristics (surface of trunk road has to be tarmac, two lanes + 
exits lanes, etc.) as these only fit in a very small region of the world 
called Europe and some of the United States of America. Rather set up 
reasonable rules for you region. As Georgetown being Guyana's capital 
has ~130.000 inhabitants this could be a good meter for scaling the 
place-tagging for example. If "village 49" has only 10 houses it might 
still qualify for a guyanese (is that the adjective?) place=village. 
More important than the raw numbers are the infrastructural 
installations found there (a shop, a place to find a bed, etc.) and the 
importance of that place to it's surroundings.

I've seen you've started a wikiproject page on Guyana already. Keep it up!

Claudius
