I think there are a number of problems with trying to get some organised campaign going:
* People have just come out of one organisation and generally don't want to get involved in another.
* Not everyone is after the same results.
* People don't have the time or the money to spend.
* Many have been victims in one way or another and are busy recovering.
Not least, I don't think that big, organised campaigns are always the thing that is going to have the biggest effect.
What does work is individuals telling what they have learned to people they know. Convince one person to leave and they may help others and in turn, they may help more. Just as families join the WT starting with one person, so they can leave starting with one person.
In time, it will grow and the tens will become hundreds and then thousands, hundreds of thousands .... millions etc...
The best we can do is to make information available, promote it where we can (given the resources that we have and that people are willing to contribute), share experiences and provide the support that people need when they want to leave.
We've already seen the growth of the WTS stop and membership start to decline. They won't get the new recruits that they once did (if I'm thinking of buying into anything I do a search on the Internet first) and I think the heart & soul has gone from the rank & file. I think their decline will accelerate in the coming years - it will be an interesting time.
