Other than being a very infrequent contributor to one Baha'i Forum (that's open to all), this is the only other religious forum I post in. I can't really comment on what happens on other forums. I mentioned in one of your threads recently attending a youth camp where we had some 50 young people attend from different cultures and backgrounds. There were a few Christians and atheist/agnostics too. A central focus of the Baha'i Faith in the last 15 years has been the development of classes and youth groups that are open to all.
To be honest its an area that still requires a great deal of work and development in my city. I was a children's class teacher for about 5 years, mainly to ensure there were properly run classes when my sons were children. They are teenagers now and it was good to accompany my oldest son on the youth camp. He is openly undecided about religion but enjoys the Baha'i youth activities on offer.
A couple from Samoa moved into our community with their two young children and they took over the classes. They have been excellent. The areas of growth in the New Zealand Baha'i community have often had Pacific Islanders at the forefront.
What has most concerned me in working with young people are the high rates of mental health issues in our communities and the Baha'is are as affected as any other group. Its therefore challenging but rewarding work.
Adrian, individuals of all persuasions can really do a lot. In many religious or charitable groups, not only are you 'required' to tithe 10% of your money, but also 10% of your time. So if you work 40 hours a week, a minimum of 4 hours a week of time donation is suggested. of course there are those in situations who can do far far more. In my experience of working with volunteers (mostly at school, the parents) it varies a lot, but suffice it to say a whole lot of stuff just would not happen if it weren't for dedicated volunteers everywhere.
