(Also, while I'm bothering y'all about encryption, have you considered
opening the secure variant of `irc.w3c.org` up to the public? The server
helpfully explains that W3C Team members can "... join the secure server on
irc.w3.org:6697, using [their] web credentials". It would be lovely if
others could do the same. :) )

>>

>>
>> * Firefox:

>> * Chrome / Opera:

>>   Under the "Delete domain" section type in the Domain field
>>   "www.w3.org" and click on the "Delete" button.

>>
>> 3. Disclaimer

>>
>> www-test.w3.org is only a test server. We try to make it work as a
>> production one but it may have inconsistent content or be down without

>> time. If you're testing it and it goes offline, please mail
>> sysreq@w3.org for further info and ask when it will become
