+- If you get stuck, ask in **#thunix** on **newnet.net**, or [contact us](/contact).
 
 **How can I request an account recovery or public key replacement?**
 
-- Just send the request from the email you used to register and we'll poke a new key in for you.
+- Email us **from the address you used to register** and tell us:
+  - your username
+  - what you need (recovery / key replacement)
+  - your **new public key** (paste it in the email)

 **What happened to the old thunix? Why the name change?**
 
-- The original machine and founder dissappeared without any warning to anyone, including server staff. For this reason, most things were not backed up, and we needed to obtain a new domain name, and a new set of machines.
+- The original machine and founder disappeared without warning (including to staff).

+  - why you want it

 **Can I get password-based login? Old thunix had it!**
 
-- No. Sorry. Not for shell access. For other integrated services, password auth will be enabled, but not for your ssh connection. We use key based authentication, as it's more secure, and more convienent for you, to be honest.
+- No. Not for **shell access**.
+- SSH is **key-based** because it’s more secure and, honestly, less annoying once you’re set up.

+# Season’s Greetings - December 2025
+
+As the year winds down, a sincere thank-you to everyone who’s made Thunix feel like a real community and not just “a server with accounts.” Whether you’re here for SSH, web hosting, email, or the other UNIX-y odds and ends, we’re glad you’re part of this little corner of the internet.
+
+If you’re taking some quiet time over the holidays, consider doing something wonderfully low-pressure: update your `~/public_html`, publish something on Gopher, poke at the Gemini capsule (`gemini://thunix.net`), or just hang out with us on IRC (`irc.newnet.net:6697` in `#thunix`). No algorithms, no shouting, just people making things.
+
+However you spend the season: take care of yourself, be decent to each other, and we’ll keep doing our best to keep Thunix stable, secure, and fun.
