You can track registrations here...
Note the E and S side and downtown (N) are low - is because very few people can register due to a bug. I live in the section on the N edge of Green loop wrapping around a couple hoods where very few can register.
Right now about 44/130 (33%) of valid fiberhoods are registered but its come to a near halt because few others are able to register.
I've tried dozens of addresses in valid fiberhoods that don't work. Sent it to the KC Star and they are silent.
