have you tried the guiders forum and have you tried the guide company or scout group on facebook, they should be able to help you, guiders forum would be better.
Register has to be done, so you know who is there in case of a fire, would assume no fire drills either? Get YLs in uniform, they are seen as leaders by rainbows, get them in uniform.
Don't deal with rainbows, but have dealt with Beavers, and also ACC (6-14 programme) so deal with Beavers as part of my role, but would say crafts is always a good start and cooking, now how good the cooking is, can be debatable.
Feel free to message me on here.
