:I tried ... I feared the move of 6 to 7, 5 to 6, etc wouldn't work because it wouldn't allow the moves over existing articles, so I tried moving the archive1 to Archive 0, in line with the others, in hopes that the talk page would pick up that the number sequence began with 0.  That didn't work, so I tried adding an explicit "mask" parameter to pick the Archive 0.  That didn't work, so I went back to trying to do the full set of moves, but the 5 to 6 move failed as I thought it would.  So I moved 7 back to 6, but now the talk page thinks 7 is an archive too.  So I've made it worse not better ... this needs the attention of an admin or a talk archive expert.
