Thanks, but that’s not going to work. The name changes are too varied – they actually overlap in places – for something like that. Maybe I phrased it wrong…
For instance, in March 2005, Poster A’s name will be on Poster B’s posts, and Poster F’s name on Poster E’s posts. In December 2005, B’s name will be on E’s posts, and F’s name on A’s posts. And so forth – we have at least two dozen authors in the system, though only a handful post regularly, and each import spawned a whole new set of mixed-up attributions. Which is why I’m looking for something that will let me change author names manually in a batch.
