Thanks so much marcos. It works wonderfully.
Now all my swearing is at mediawiki deployment complexities that have nothing to do with you guys. Like much OpenSource, mediawiki is interspersed with some design brilliance, 100,000 unclear configuration options, wrapped in unreliability and inaccurate or missing documentation. (Why can't simple backup/restore databases actually work? There's 14 ways to do it, and they all have different "issues"). I need to find a good contractor that really knows this thing.
But you guys have been fantastic -- I've dealt with paid support that wasn't nearly this helpful.
