Bad news. The server hosting The Ruby Toolbox went bust on the evening of June 7th. While I do have backups, the original source code is in a very outdated state so I currently don't feel it makes sense to try and get it running again.

For the time being, here is a very stripped down version of the Ruby Toolbox's contents.

Update June 13th: I'd like to invite you to join the discussion on the future of the Toolbox on github. You can also get in touch directly on Twitter.

mailboxer

A Rails engine that allows any model to act as messageable, adding the ability to exchange messages with any other messageable model, even different ones. It supports the use of conversations with two or more recipients to organize the messages. You have a complete use of a mailbox object for each messageable model that manages an inbox, sentbox and trash for conversations. It also supports sending notifications to messageable models, intended to be used as system notifications.
