Dear OSM Mappers, 

(please apologise, I don't speak Serbian)
due to the upcoming licence change from cc-by-sa to ODbL I have made some 
investigation, how Serbia would be in OSM after the licence change when data 
from users, who do not agree will be deleted.
I have measured by nodes edited or created in Serbia, incl the provinces Kosovo 
and Vojvodina. Final OSM calculation may differ. My calculation is to estimate 
the data loss

48 OSM users have created or modified 94% of all Serbian nodes. 26.5% of 2 users 
(nr. 1  and nr. 6) are probably from a data import in Kosovo. Excluding them 
(both have agreed to the new licence) would make it even worse.
If the licences would be changed today, 47% of all data of Serbia would have to 
be deleted. 

If the Kosovo data import would be excluded from the view, the number of nodes 
that will be deleted will increase to 64% !!

If you want to help since there is still a lot of time left until the licence 
will be changed:
1. Agree to the new licence if you feel that the new licence is something that 
you can agree on. You can accept the new licence here 
http://openstreetmap.org/user/terms
2. If you know someone from the list, ask them. 
3. Contact the people with a "no" and ask if they want to agree
There are some Germans on the list, I will ask them.

Kind regards
