Well, this is a busy forum... probably all off playing modified Minecraft,
However, if this page ever gets visited again consider looking at ATLauncher, I'll say that again so you don't miss it...
It currently has some 45 modpacks to choose from and server thingies for those who wish to play with their mates and/or the rest of the world.
Currently most modpacks run 1.7.10 so are stable 'or as stable as any modded game is' and I personally run modified modpacks with bits bought in from some of the various modpacks that are available, it's well worth checking out as a source of excellent packs most of which are fully configurable.
As ever Pete
