We will very shortly be upgrading the website to a more recent version of the framework software (Ruby on Rails 3.0). You probably won't notice much difference but it is a very big change that has required months of work. We're very close to being able to deploy the new version. Unfortunately, as happened this morning, there is a chance that as we test the new framework, the current site will come crashing down. We're hoping to minimize the outages as much as possible but if you see cryptic error messages and can't login, it's because we're stuck halfway down the upgrade path. Sometimes it's difficult at that point to know whether to try to revert back or keep pushing forward.
Update: our hosting company has decided to upgrade the entire server now so there is a small chance Memverse will disappear for a short while. Fear not, we'll be back.
