We have moved to Discord.
Here is a link to the Discord server. If you are opposed to using discord... I'm sorry to hear that. It is a great client that allows a lot of voice and text chat channels per server AND you can check other servers without having to log off and on. It's good. You should use it.
As for [email protected] it might not be dead but I'm 98% any Minecraft version won't be coming out. Who knows. A lot of us are hanging out on Discord and playing other games. Feel free to join us or add the server to check in every now and again.
