I have at least started OSM wiki articles on the major cities of Turkmenistan, as follows:

*Ashgabat *Balkanabat *Dashoguz *Mary (Turkmenistan) *Turkmenabat *Turkmenbashy

The intent is to institutionalize all I have learned about mapping in Turkmenistan so far, before my tour of duty ends sometime this calendar year. If other mappers have suggestions for information to add to these articles, I am all ears.
