How does one disable the MUC roomnick lockdown feature or remove the
lock on an existing roomnick? Does this require Mnesia hacking? I think
someone told me once but I lost the email or IM they sent me... 
Thanks!

I don't see any option to disable it.

The MUC service keeps a list of the registered nicks, and the
corresponding JID in the Mnesia table 'muc_registered'. It is easy to
delete an item in that table if you have access to an Erlang shell
attached to the running ejabberd node.
Another solution is to impersonate the JID and unregister the nick
with a Jabber client. This is quite difficult if the Jabber server
does not exist anymore.
Yet another solution is to wait until somebody implements in the MUC
service some pages for the Web Admin, including a page to delete MUC
registrations. I doubt you can wait so much

Thanks! I'm sure I have access to the Erlang shell at jabber.org, but
I've never used it. Time to experiment.

Note that I said: an Erlang shell attached to the running ejabberd node.
If the JID is user@server and the MUC service is
conference.example.org, then try something like this:
mnesia:dirty_delete({muc_registered, {{"user", "server"},
"conference.example.org"}}).
ok
Remember the dot at the end of the sentence. Note that the answer will
be 'ok' even if there was no record to delete.
If the Erlang shell is not attached to an ejabbed node, you will get this error:
** exited: {node_not_running,nonode@nohost} **
Once finished, to exit that Erlang shell that is attached to a running
node without stopping the ejabberd node, the best way I think is:
control+c, control+c.

Yes, I got that going:
erl -sname node1 -remsh athena@athena

In fact I was trying to unlock an existing roomnick (we'll call it
"thelockednick") that was associated with the wrong person, so I did this:
mnesia:dirty_index_read(muc_registered, "thelockednick", 3).
That enabled me to discover who owned the nick (we will say it was
"foobar@example.com").
Then I could do this:
mnesia:dirty_delete({muc_registered, {{"foobar", "example.com"},
"conference.jabber.org"}}).
Voila!
Thanks to badlop for the help.
