Yes the site has been down since Wednesday morning, Nov.27. The webhosting company had some huge problem with their server that took the site and related mail server completely down. Even worse, they lost their backups of the database -- they lost everything. Almost unbelievable. Lucky for me (ok it's not just luck) I make a backup of the site database every single morning and download it to my computer; in fact it was when I went to do that Wednesday morning that I discovered the site was down.
We are working as we speak to get the site back up with the site database restored from my Nov 26 backup, at which time all the accounts and listings should be intact.
