Hi Silvergirl,
I'm an Explorer Scout leader, and my wife is a Guide leader, so I've seen how both organisations work. I'm very surprised that you have been asked to pay the membership fee - I thought this was always paid from group/unit funds, and generally uniform is half paid for out of funds or a set grant is given. Training is generally paid for out of funds as well, so have a word with your district commissioner and ask her what is acceptable in your area.
I've not looked round the Guides website, but the Scout one (scoutbase.org.uk) has loads of free donwloadable resources on it, fact sheets Etc. and there is the programmes online database which is also crammed with info.
Guides is slightly different to Scouts in that there is much less of a group structure, the Guide leader tends to be in charge rather than having a Group Scout Leader and an Exec committee, which can lead to less politics!
Getting back to the original point, is Scouting losing it's way, no, I don't think it is. We will always be dependant on good leaders and they go in cycles. In the group I grew up in there were great leaders, but they've all since moved on and the group has gone downhill. This was due mainly to personality clashes in District. I'm now in a different district and it's doing very well, a completely different story.
Training should be available to everyone and obviously new leaders will need more of the basic scouting skills training than more experienced ones, but all leaders should get 'teacher' training as well as 'scouting' training. If your district isn't pushing or advertising training then get in contact with your County, they will certainly be laying on training - you just need to know how to find out about it.
ilan said that there doesn't appear to be a curriculum, there is, it's called the 'balanced programme', for cubs you can find it here :
http://www.scoutbase.org.uk/6to25/cub/programme/zones/index.htm in addition to that there are loads of badges and awards to work towards and in doing so you are following the curriculum. What you actually decide to do from one night to the next is up to you, you choose what you think the kids are interested in and what you can manage to arrange.
Scouting is evolving, it has to. Some of us would like to see more of the traditional stuff and don't like the clamp down on rules for adventurous activities for example or the dilution of uniform (we used to be very proud of our berets!) and ceremony, but it's taken me a while to see that if it didn't evolve along with the rest of the country then it would slowy die out as it became more specialised. I've come to the conclusion that it's better it changes and keeps going, than keep it traditional and have it die out.
Sorry, that went on a bit! Hope it's helpfull to someone!
