Request rollback of other user changes

Hi guys;

Today I saw some mapping errors in my town. Actually a month ago those streets were okay, but it seems that a new user, trying to understand the editor features, saved wrong data by mistake.

My question is: is it possíble to rollback these changes?

I’ve checked the history and know the dataset numbers, all from the same user (Rafael Gouvea):

Yes, it is possible to revert certain changesets, see http://wiki.openstreetmap.org/wiki/Change_rollback

I recommend to ask an advanced OSM user to do that if you are not familiar with extended use of editors.

Or ask at the OSM IRC channel.
