OTR.im was started to strengthen the OTR community by providing a hub where developers can find each other, improve their respective projects and contribute to the OTR community.
We also want to provide new and/or existing projects with hosting, i.e, giving them access to the bugtracker and git repositories. As of now, along with libotr, the pidgin-otr plugin is also hosted there.
However, OTR.im is not a replacement for otr.cypherpunks.ca, it is merely an addition to the community as a whole and a way to do the project hosting.
There has been increased interest in OTR and mpOTR the past few months. In April 2014, the Debian OTR team has been announced. Furthermore, a group of cryptographers and developers is working on an mpOTR specification, which would allow more than 2 people to chat with each other using end-to-end encryption.
This initiative was brought to you by the useotr folks, who are dedicated to strengthen the OTR ecosystem and bridging gaps between users and developers. Since Snowden's revelations have been published the need for secure end-to-end communication has become clearer. We aim to help out with providing that. In collaboration with the libotr authors and the various implementation developers.
Last but not least, get involved.
