We have just started a new website and XMPP server: Tigase.im.
This is a mixture of the Drupal CMS and the Tigase XMPP Server features where we want to provide users with a very close integration between these services.
For now this is just online account management but soon we want to offer much more. Ideas are endless and probably we are unable to make them all real on our own. Therefore, we encourage you to join. Simply use the service and enjoy it. If you are happy to contribute or just trow ideas you are very welcomed too.
Check the website for all the details.
