contact ratings help Options

[makari]

I'm rounding out a character and found a couple of contacts I wanted to get, but am having a very hard time determining the cost for them

in the advanced contacts in runners companion, it lists the exchange, and I've read about it in other places, including one that suggests how to use it (every run roll 3 die for the exchange and 3 for the character, a tie nothing happens, if there's a winner then he gets a favor with a rating equal to the successes... if the character lost he gets asked to do a favor of that rating)

however, I'm having a hard time putting a point value on the exchange to start with... I wish when they gave these examples they would have went ahead and listed their modifiers....
from what I can gather, one of the sidebars mention that there are likely thousands of members so I'm guessing membership +6 modifier... area of influence? I'd assume with the numbers limited to thousands thay are in a single sprawl but would you really give them any influence since they dont really do that like a normal contact? and then magic and matrix resources... I'm thinking just 1 of each but I'm not sure how to handle that again since these resources dont get called on like a normal contact again... and for that matter with the way this contact would work I'm hesitant to make it cost the +6 mod for membership.... and I'm not sure how to handle loyalty or connections base for them at all...


another one is the Warezhouse 24, a hacker, software group... it lists their members as 87 I think it was so +2 membership, but how about area of influence... it's matrix based and even mentions that the main hardware is on some legal remote location, but again I'm hesistant to give it the +6 global modifier simply because it's a matrix based group... especially one so small

any suggestions or comments on how to handle these?
