Ok, Thanks, you don't normally have to roll against other characters, it's unfortunately up to them how they react. When rolling a skill, clarify why you are using it in the roll, like:
Leadership -> disarm for meeting
It will help later on, and allows me to tailor the responses to better fit what you were trying to do.
Also sorry for shooting down Voodoo's Hacking attempt, The trace was fine, but past that you would need to scan to find the hidden node, since intercepting traffic only really works on Wired connects, it specifically states you have to know where all the info is passing through and wireless connections get difficult with range.
