Indian Pirates have presence on Matrix, XMPP and IRC. All these three chatrooms are bridged to each other which means if you join any one room your messages will be synced across all the rooms. More details about each room is given below.
You can either join as guest from a web client like https://chat.diasp.in (If you aleady have a diaspora account on diasp.in then you can join with the same login credentials) or you can join from a matrix client like Riot which is available on Desktop, Mobile and Web.
You can use any XMPP Client to join the chat (for example Pidgin for Desktop, Conversations for Android, etc). You can find a list of XMPP Clients at http://xmpp.org/software/clients.html. If you are new to XMPP (also known as Jabber), you can use the free online web service located at https://conversejs.org to login and join the chat.
If you don't have an XMPP account already, you can register for a new one at diasp.in or disroot.org or at any other XMPP Providers listed at https://xmpp.net/directory.php or http://www.jabberes.org/servers. Also check https://podupti.me for a list of Diaspora Pods with XMPP support.
