@mairaw Build is complete and now showing up on stage. All previous issues addressed. Finally ready to merge?

[mairaw]

Ok, things are looking good now. But I do have another question now:

• You moved the content of the gc-overview file to the index one inside garbagecollection right?
  So now we have two topics with the same GUID. You should apply the redirection metadata to the original one since folks could have links to that.

@mairaw Shouldn't be a problem - I found one topic that was linking to it and fixed the broken link.
And actually it was the other way around - I copied the contents of the old index file into gc_overview, then moved it and renamed it to index.

[mairaw]

But you now have two valid topics with the same GUID and the old one is still searchable and reachable, just not on the TOC. You need to apply the redirect on the old one.
