Probably because It costs both time and money to provide such a service, and unfortunately not everyone's able to dedicate free time especially if it's a high quality and professionally staffed offering rather than "hobbyist". And as membership's increased so will have the costs of increased resources (web servers and software) as well as relevant expertise.Phew! That's a relief.
Why the change I wonder? Maybe going to go more hi-tech?
Sorry about the "essay"!
