Dear anas1307,

you have just removed a sizable portion of London on our production database!

I'm sure this must have been a mistake; maybe you didn't know that the production database would be altered, and you assumed that you were just making changes for yourself.

Please familiarize yourself with OpenStreetMap, ideally by reading the beginner documentation available through our Wiki (wiki.openstreetmap.org) or participating in Forums or mailing lists, and be a little more careful next time ;)

I have reverted your edit and restored London to its former glory.

Bye
