I think you could try to register using ttarrant+wildfly(a)redhat.com address is you are on
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.
