In answer to an email yes it is in addition to any money you get from the normal 50/50 recurring.
example:

10 Sales

7 buy trial @ 14.95=104.65
3 buy month@ 34.95=106.85

your 50% Share 104.75

Lets say 5 recurr after 7days @ $34.95= 174.75

your 50% share is another $87.38

PLUS the $150 bonus being the first WM to send 10 surfers.

Your grand total for 10 surfers could easily be:

$342.13

Not Bad huh?
