Switching usernames has now been fixed for both the new and old control panel.

Regarding the continued "not being logged-in" issue that some of you have been seeing, I believe the issue has to do with proxy servers (computers that route data between Tabulas' server and your computer) are storing bad cached copies of your content. I have started explicitly telling those proxies to stop caching - I hope this resolves some of your login issues.

These effects may take a little while to resolve, but please continue to report to me any issues regarding login states that are not consistent with what you expect. Thanks.
