As many have noted the call to action and petition --which has now nearly 900 signatures! -- initiated by Martin Kusch and Mark Lance among others "is much more specific and prescriptive than the actual Gendered Conference Campaign has been." So, a new official petition has been launched by the GCC "that is more closely aligned with the GCC's methods."
As I write this over a 100 signatures have been gathered, including from lots of folk on the original (non-official) petition. This "official" petition is also drawing on folk that have publicly or privately expressed reservations about our call to action; it is great to see them drawn into the GCC, which ought to be embraced by the whole profession henceforth!
