Flickr Help needed

Good morning from Beijing.

We are 10 days into the Chinese New Celebration with only 5 days to go. Why do I mention that? Because it has been relatively quiet at nights except for the 5th and the 10th nights when fireworks again burst on the scene. Now we just have to wait for the 15th day (night) for the Lantern Festival which marks the official end of the celebration with another round of hours of fireworks until around midnight. Then there will be blessed peace again. :0

What does this have to do with Flickr? Well, I am a late comer to Flickr as it was blocked in China for a long time but it has been open for about 18 months and I am slowly figuring it out. I have pictures and videos of last year's chinese new year's celebration that I want to post so I am learning.

More important than my personal use, though, is the fact that I want to use it for my students (Grade 4.Year5) to post pictures in a safe and closed environment. Under my name (toadie1951) I have created a group called Year 5DR. Up to that point I am fine. Now the problems begin.

1) how do I get my kids into the group? They all have their own email addresses but only two belong to Flickr. I can't figure how to do this?

2) As the adminstrator am I the only one who can invite members and approve members?

I have searched You Tube etc. for help but am not getting much....

Would appreciate any suggestions.

Thanks
