We’ve deployed a new instant messaging system based on the Openfire server and Spark IM client that has strong security and a lot of great features. Getting up and running only takes a few minutes. Download the installer from:
Once you’ve performed the initial installation, the client will automatically notify you when updates are available. When the client starts, enter your username and password along with the server name hub.chatnsn.co.uk. Registration can be done via the client once installed.

PLEASE NOTE: Due to recent changes to openfire and spark, after updating, you will need to go to advanced settings before logging in, and make sure both ‘accept all certificates’, and ‘disable certficate hostname verification’, are ticked. Without these settings enabled, you will not be able to sign in. This is beyond our control unless we set up additional complicated dns records.
