== recent edits == 

 I have had to revert a chunk of recent edits by Caledon861 (see my revert here.  The edits were made in good faith, and some of the material probably should be retained,... unfortunately some of the changes were unsupported and contentious, and I can not separate out the good from the bad and so have had to revert it all.  I ask Caledon861 to go a bit slower... make a small change, then wait until others have had a chance to see it and comment (say a day or two), then move on to make the next one.  Thanks.
