Did not see any posts for this show, so figured I would let those know about it.
There are 3 seasons now- the 4th is planned sometime this year. Stars Tamsin Greig (Black Books)- BBCA aired only season one, I was able to get all 3 series on Ioffer- Hilarious show- recommended if your looking for a new britcom you may not be aware of.

This show really needs to stream on a service in the US, or the series be available
