Here we can discuss anything about this Lemmy instance/server itself.
Our XMPP support chat: Movim or XMPP client.
I think for the occasional post https://slrpnk.net/c/energy or https://slrpnk.net/c/technology will do, no?
Of course if you want to go all out and post a lot of hydrogen related posts, better make a community for it (and actively moderate it of course).
Hi there! Looks like you linked to a Lemmy community using an URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !energy@slrpnk.net, !technology@slrpnk.net
