First, two common kinds of messages which should not go to any TeX Live list:
Here are the TeX Live mailing lists (they are all hosted on tug.org):
You do not need to be subscribed in order to post to any of these (or other tug.org) mailing lists.
You can use the web interfaces linked above to (un)subscribe if you wish (they are open lists, except for tlsecurity), or peruse their archives.
All the archives are public (except for tlsecurity). Thus, if you do not want your name or email address to be publicly visible, don't write to these lists. But in all other cases, please do write to the lists, instead of to individuals.
