OK, I’ve got this figured out. I had to find a discussion of it, where people complained about Flickr not documenting the procedures for private groups well enough. (I had made us a public group by invitation only, though I had promised you all a private group, not viewable by outsiders.)
I have to invite you to join — you can’t ask to join. You have to email me so I can invite you.
If you have already joined Flickr, I can use either the email you used to register with Flickr or your Flickr user name. It will automatically make us contacts (which is not great) but we can delete one another from our contacts without it messing things up. If this last part makes no sense to you, ignore it for now. You have to email me & tell me your username or the right email to use.
If you are not a Flickr member yet, pls do this:
1. Join Flickr
2. Email me your Flickr id
3. I’ll send you an invitation
As above, it’ll make us contacts but we can change that.
I’ll try to turn these around as fast as I can.
