Good for you dgp, the great thing about bigger cults like JWs and Mormons is that their record is now out there for everyone to see. Both their own record from what they have printed and a critical analysis of their work by outsiders and yes *gasp* former members.
Its a matter of time now. It will probably take a few more "generations" (yes, actual generations, not WT defined) before the JWs shrink significantly. But as long as these inept leaders continue on their warpath of "obey or die" without offering anything of real benefit by being part of their religion I see no way they grow beyond the 8 million or so they have right now.
