Ok here is setted up also the Advanced css github repo with already some sketchs about the topic we would prepare.
Fell free to start to edit or comment.
@Bettina you can already give this 2 repo as a refereed link to coaches, so they can have an idea what would be the workshop.
I personally think is time to find coaches 
So i wrote in the js coaches mailing list, can you @Ben or someone else write a blog post about?
And @Bea can you or who else have the access, write on fb/twt?
We can give to coaches this discourse as a referring point where write us/find us.
The css Conf is Friday 14th so we could give to the coaches a date between 18 and 27 Sept. as possible evening for the first meeting.
We should also go on tuesday at up.front, announce the workshop and find coaches.
@Ola will be super nice to meet you in person. When exactly you will be here in Berlin?
