The rebuild is complete!
For everyone who has expressed concern, thank you. Our host had upgraded Drupal, the software that runs this site, but one of the plugins was not compatible with the new version. All attempts to remove the plugin or downgrade the software failed, and since the database contained information about the installed plugin, it could not be used to restore the site. The front page content was visible and accessible as normal, but we could not update the site on the backend, which meant that we could not post any new content or edit any existing content.
But now we're back, with all the content we had before, and everything is working as it should. For now.
We will reopen to submissions on April 15.
