Where is this elusive MLS that's exlusive to RE agents?

[Brian Paine]

So, I keep hearing that to get access to "The MLS" you need to have your RE license... Which I'm working on BTW. Yay me!

So, googling around there does not appear to be one official nation wide MLS.

All the sites that claim to be "an MLS", such as MLS.com provides access to the public. So, they are clearly not "The MLS".

What am I missing?

Thanks,

Brian
