Looks like Hipchat reset the urls for guest login
as for registration goes, you can create account with + notation which can
be mapped back to your account.
so you create account with mail ttarrant+wildfly(a)redhat.com
and it should work.
Hipchat client supports logging into multiple accounts for a while now.

I've complained in the past about the WildFly's team decision to move to
HipChat, but I've always been able to access the chat room as a guest
using the link provided on the homepage 
Unfortunately that link no longer works, since it expects me to register
with an e-mail account. Considering HipChat's stupid policy that
disallows a single account to join multiple groups, I'm unwilling to
"sacrifice" an e-mail address just for the few situations in which I
need to get hold of one of you.
Please fix it.
