yes, I've written to BPach who did place it there, as well as the only other cacher who logged being there after it was placed. Magicman/PookyBear say it wasn't in the cache. But these other two logs were in the book before them, that's why I'd like to contact them. So, yes, welch, I've exhausted the obvious, including emailing the Bug owner.
And I don't consider it practical to bash the geocaching servers to brute force search the user database.
