Thanks for the great write up Sarah.

We would love user feedback / testing on these two themes as they stand, currently we're updating them progressively, but opinion is appreciated on how they respond for people.

One of the aspects we have tackled and focussed on is getting a good layout working for mobile and small tablet devices so feedback in that area is useful.

Hopefully with this project we'll demonstrate the usefulness of being able to drop additional companion styles into any new WordPress default theme and be able to showcase BP at it's best in them, also with this project we introduce scss pre-processing to BP which allows us to better manage styles.
