37signals launches online planner

37signals, authors of the now fashionable Ruby on Rails technology, have launched another project, Highrise . In general terms, this is a scheduler, contact manager and notebook, with the ability to insert multimedia, and the presence of some kind of collaboration (by the way, there is integration with Basecamp - at least you can import contacts).

The service is mostly paid. Of the 6 tariffs, only one is free, allowing you to keep up to two users and 25 contacts on your account. SSL or file uploads are out of the question.
