We recently discovered that the application to join the OBF (linked from the OBF membership page) was not working. It broke some time after August 31. We have now replaced it and it is working once again.
If you applied for OBF membership between September 1 and yesterday, please go to the new form (https://goo.gl/x9KYWL) and resubmit your application. We apologize for the inconvenience!
