Welcome to the thread Akulisto, glad to see this group has caught other eyes, and I actually haven't seen the pictures you posted which means you must have an inside track on this group!
There's a few new faces in there for me to try and track down - and a couple I recognise but haven't yet posted. I look forward to more, from you, all I get are the ones Dima and his friends decide to make public.
I've managed to ID the third girl in the -27 set, a young lady called Lyusha K. (I say managed, it's very easy when they tag the photos!) Here's some more pictures of her - look for the tartan headscarf in the sauna.
