I started one right after Rockingham was released before the holiday and I worked on it again just yesterday. It's a rather challenging layout with nasty narrow zones where you need to be careful.
I hope some people like it, I find it fun with the LX4 with a very short gear ratio.
Edit: I improved it again.
Edit 2: I reworked on it again, quite more than what was planned but I think it's worth it. The RB4 is quite fun with it but the first sector is pretty tight (you'll know soon enough if you try it out). I uploaded a replay I've just made using a gamepad for those that wants to see an onboard lap before trying a new layout.. because it's not always obvious to "get" a layout from someone else.
