I found a Minecraft server that is all about the Boomcrafty modpack.
The main thing here is playing modded Minecraft together and using the modpack for the full experience.
If you want more info it points to the Boomcrafty modpack page.

I found Altar SMP and it is a new SMP that is about to start.
It is starting tomorrow so it feels like a good time to join early and not be behind.
They say it is going to be big and it has good plugins so it should be a solid setup for survival.GG.MINEWIND.NET New Server IP
