What if I don't already have a Jabber account?

No problem! Set up an account for yourself at: www.jabber.org. Your Jabber ID will be “name+company@jabber.halloo.com”. Use your client software to create this account on the Halloo Jabber server: jabber.halloo.com. Feel free to give out your Halloo Jabber ID and use your Halloo IM account as a standard IM account as long as you keep your Halloo phone service.
