DO NOT, i repeat, DO NOT use MAS. i have used it in the past for both small and larger affiliate programs. the MAS program is difficult to use, lacks a lot of necessary features, is very slow and does not allow you to stream videos.

i basically had to tear the thing apart and re-write a ton of code and my own modules to get the thing to work properly.

the thing is just a mess, PLUS they want to charge you like $5000 or some crazy amount like that....plus every domain you have is an extra "x" amount of dollars.

the only good thing is that Ross and Mom that provide support for MAS are very nice and provide excellent help.
