I have added a ZNC instance for tilde.club users. Any user that signed up prior to December 28th 2021 will need to email root@tilde.club and let us know you want a ZNC account. All new users will have the ZNC account setup automatically when account is created.
I have updated the Wiki to mention the ZNC that is available. You can find it at: https://tilde.club/wiki/irc.html

If you have any questions or suggestions for other services we should offer, please do reply to this or email root@tilde.club or find ben or deepend in IRC.

Enjoy!
