I thought I would do some quick testing on my working copy of Psi to figure out what needs to be done next for MUC. I fired up the affiliation editor, and as expected I get an error message due to my query for affiliations that are 'none'. The message box is essentially empty and I was wondering why since I handle error stanzas in the Task. Looking at the XML that I received mu-conference (am I correct that this is what j.org is using?) there error stanza was tucked into an <item> element. I then checked JEP-0045 to see where the error element was supposed to appear. Turns out mu-conf isn't working correctly—again.
I have to ask, must I support these "features" or go with the JEP (which needs some work, or to be phased out in favor of MUC+)?



try with other MUC implementations
You also can try with other MUC implementations:
* ejabberd cvs (in 0.7.5 there was a small bug, which is fixed) should be MUC compliant
* Jive messenger also has MUC support AFAIK
* maybe Chime also has a MUC?
ps: What the f*ck is an "email address"; I just entered my JID, I hope this is ok ;-)
