Sorry I didn't reply right away, I think Paco might have even emailed me about it earlier, actually...oops, sorry.
I suppose the next time Locke_gb7 emails a submission in I should take note of his email address and ask him if that's what he wants to update his broken email contact link to. So I'm sure we'll get a hold of him soon, as he's probably still actively mapping.
But I don't think there's anything we can do about email contacts that are dead for one-time or long-ago contributors. As per my habit of deleting submission emails once I'm sure the maps are up, I'm not likely to have their contact info if it's not the same as what's on the site or the forums.
