I just uploaded changeset http://www.openstreetmap.org/changeset/34556318 with the wrong account by accident- AlbertP_BAG, which is only intended for imports from a Dutch data source of buildings and addresses, instead of AlbertP.
Are you aware of any way to correct this?
Maybe add an explanation in that changeset’s discussion.
What has been done, cannot be undone… Actually it can, the existing editing history can be altered in so-called “redaction process”, but they do it only in very severe cases (e.g. to remove copyrighted data someone illegally added into OpenStreetMap). For your case, just avoid doing such mistake in the future 
Thank you for the reply, I’ll add a note.
