[OSM-talk] Editing of content that will be deleted on April 1st

[Simon Poole]

Sorry but Frederik and my numbers (odbl.poole.ch) are compatible 
(odbl.de naturally not, RTFM). Just because some areas look like a big 
red blob, doesn't mean that are lot of useful (ie non-imported) data is 
being lost, look at  Spain for example.
