I have an 8x and it's maddening. not sure if you're aware, but if you sign up to Verizon Messages through My Verizon online, you can then manage groups that way. and when you know you've received a group sms, you can launch internet explorer on your phone and go to the Verizon Messages website and participate that way. It's not seamless at all, but it is a workaround...
I have found the "Rooms" option built into Windows Phone to be the best group chat/sharing option. This is not advertised well enough, it is a really powerful feature.
