After lots of weeks in development we just launched a new version of Nada with a better faster UI and new smtp server engine. Unfortunately during the upgrade we managed to destroy the DB with all old messages. As part of learning how not to f**k up again we will build a development environment where all new versions will be tested thoroughly before getting out of the door.
Sorry about the inconvenience and do let us know what you think about the new version or any features you think are missing.
