I need a Web-based XMPP client that can be used with any Jabber ID.
Ideally without having to create a user account on the website, so
- let me directly login with my existing JID and password,
- show my roster, any offline messages, let me chat,
- let me log out,
I don’t need support for anything else, so no need for status messages, chat history, file transfer, Jingle, MUC etc.
