Minecraft mod that adds servers?

So, I know this is not the best place to ask this, but I'm much more familiar with Answers than any of the many minecraft forums. Anyways, I have the technic launcher and I recently found the crafting dead. I installed it and started playing(It's great) but then I clicked multiplayer for random unimportant reasons and the mad add servers that you can play in without having to look them up or do anything extra. This was absolutely freakin' amazing, especially since I have issues with how minecrafts multiplayer servers work. So I got to thinking, and it would be amazing if there where any other mods or mad packs that did this, because even though the crafting dead is great, it is most definitely not my favorite way to play. I have FTB, Technic launcher and regular minecraft, modded and vanilla versions. Any answer is helpful, unless it's not. ^_^
