I am now the event manager for Wikimania and was told by our programming chair that I should ask for ownership of this list: email@example.com. I was told by @Rfarrand that you may be able to help.
We certainly can! (I'm on SRE clinic duty this week, hence handing ML requests too)
Which email address should we be adding to wikimania-program list? Also the current owner (firstname.lastname@example.org) should be kept?
You can add new subscribers to the list at this page:
If you need another admin, or a 1:1 meeting to explain part of the software, I'm willing to help (email@example.com). You can add other admins at this page:
Also, what is the difference between a list and a google group?
Technically: Mailing list addresses that end in @lists.wikimedia.org are GNU Mailman lists, so you can manage your subscriptions and browse any archives at https://lists.wikimedia.org. Those ending in @wikimedia.org are Google Groups, so you would do that at https://groups.google.com instead.
Sociopolitically/etc: The movement started off with just a Mailman list and the wikis (see detailed history), but has been fragmenting across additional platforms over the years, and more so recently. (cf. https://xkcd.com/1810/). Mailman is open-source, but we're currently using a very outdated version (v.2) partially because migrating to the overhauled new version (v.3) is hard because of our prolific usage (1,114,671 posts, currently). Google groups offers some different features, many of which are especially useful for WMF staff, but is closed-source and run by a large corporation (to put it diplomatically). Many other factors/perspectives, too.
@ICueva Also there is the listinfo page at https://lists.wikimedia.org/mailman/listinfo/wikimania-program which describes the list and where users can request to be subscribed themselves. If you want to you could even edit the contents and design of that list info page via your admin interface. You can also change a whole lot of other settings as you like.
