Apart from the great question about "Research Assistant - update to "Edited 50 different tag wikis bodies"?", a related question is like so: "Does a copy editor with rep below 2K still earn any rep for a wiki body edits of a tag that that user never suggested an edit for before?"
About a copy editor: Edit 500 posts (excluding own or deleted posts and tag edits) ... Combined with "each accepted edit suggestion results in a reputation Increase of +2", this implies that you did gain 500 x 2 = 1000 points because of those 500 accepted edits ... I assume.
Reason why I'm not sure (without further investigation): a copy editor doesn't get any more +2 reps for each additional suggested edit that got accepted. So how would one explain/motivate that accepted edit suggestions for tag wikis and/or excerpts still results in +2 reps then?
