The problem in which all users appeared as user "rich" has been fixed. I fat-fingered a manual database update earlier today and applied a change to all users which was meant to be applied just to me. I've restored the user information from last night's backup.
If you've changed your password between 3:00 AM EST (GMT -0500) and now, you will need to use your previous password to login. If you made any profile changes between then and now you will need to make the changes again. No information outside user profiles was lost.
If you are one of the four users who registered after the backup and before the problem occurred (and who are now User4731 through User4735) please <a href="mailto:rich+chiff@lafferty.ca">contact me</a> and let me know what your username was so I can change it back.
I apologize for the inconvenience.
Warm regards,
--Rich
