Due to the overwhelming number of services in the customer support space at this time, I've decided to end Feedline. It was a fun product to build but there are loads of great apps out there which are affordable and often free and are all better supported than Feedline.
Feedline will continue to work for its existing users, but we are no longer accepting new registrations.
If you're looking for a great alternative, check out Crisp! It's a great little service I highly recommend.
