I am planning to write a review (well, add some notes to the pictures) but in the meantime you can find some pictures here
https://www.dropbox.com/sh/75a9zgeztx0h6tw/AABqiPF5dpciNVg8mdJxynYRa?dl=0. I have to re-do them when my hands don't shake so much (or find my tripod) and adjust the lighting, but hopefully they are useful for the moment.
The containers you can see on the RHS of the box are variously sized as follows (all dimensions cm, as accurate as my poor eyesight allows)
7.8 x 7.8x5.8 deep
4.3 x 7.7x5.8 deep
4.8 x 3.6x2.2 deep (4 off, stacked 2+2)
7.8 x 3.8x5.8 deep
6.0 x 7.8x5.8 deep
The notches on the tile boxes are spaced with centres approximately as follows (in cm):
0 (inside box face), 2.0, 2.95, 4.3, 5.6, 6.45, 7.8, 9.1, 10, 10.9, 12.2, 13.1, 14, 15.25, 16.6, 17.5, 18.6 (end box face). These are asymmetrically spaced along the box length.
As supplied, you can't completely adopt a 'divider in front' or 'divider behind' strategy as there is not a notch at the very end of each box. I added a notch at the very end so I could have all my dividers behind the tiles to which they refer.
The box will hold ALL expansions for Carcassonne (after some fiddling to get everything in the right place) with a little bit of space left over for some fan expansions etc (maybe 30 tiles or so).
Sorry if this post is a little incoherent, I have yet to work out the formatting codes and how to embed images.
PS: I wonder if the person who defined membership levels knows what 'cottaging' is in the UK and what sort of things a 'cottager' gets up to
