any possible solutions for windows users? I ask as the reason I posted
in first place is my friend installed ejabberd for windows and didnt
work out of the box for him do to this issue.  I was able to get it
working for him with -name though, so he is fine now, I just imagine
its a common problem.
Anyways thanks for looking in to it and letting me know it will be
supported and maintained.
