Chained payments approval process


I am totally new to this site but am happy I took the discion to join.

However at the moment I am really confused on how to gain approval for the Pay Pal chained payments API in Market Press.

Have found myself bouncing around inside here and Pay Pal X developer site and have ended up with more questions than answers.

I have noticed that some of you have gone through the process successfully and wondered if any of you had written a roadmap of the whole process from start to finish that you might be willing to share.

All the best and thanks in advance
