Enroll as many of these as you can. Their influence on tomorrow's generation is tremendous. Cooks are as important. No matter how sensitive people are towards animals, if you don't show them that they can enjoy their veg and pulses it might not be easy to convince them. Include food at every opportunity.
Meals are the best form of socialising.
But they can also become boring if we do not use some imagination. Combine meals with other things, eg show a video and have a meal afterwards. Organise a good strong cooking team. This can also be one good way of networking with other groups. One example from Malta was the case of a society known as the Island Sanctuary, young volunteers taking care of 150 abandoned dogs.
