I have been running Slicing kinda loosely compared to the rules in the book (I like to make skill uses more interesting than the strict uses in the books). Often times as skill challenges so the DCs have been different based on the difficulty of the SC. This time is probably one of the first times I have used the books rules since I was not running this one as an SC figuring you were going to be "One and Done" with getting the data.
In this case I was still allowing you to access information even though the computer had a hostile attitude so I used the modifiers based on the computers attitude toward you (found on 76 of SWSE Core Rules) and modified the DC for specific information which started at a 20 so that DC was a 30 and you hit it with that original roll.
To improve access you have to use the Computers WILL and add the modifier for the computer's attitude (really it is subtract from your rolls but since this is PbP it is easier for me to modify the DC up and allow you to just roll your checks the same way every time) for the DC to improve. If successful the computers attitude improves by one step. Hope this helps answer the question ( I know it is not the answer you are looking for in every case though).
I will be adding another post to our games section for Missions. Sort of a reminder of the ultimate goals of what the party may currently be focused on accomplishing. I think over time (because PbP is so slow and many players are in multiple games) its harder to recall each one. It will update as missions are completed or new ones are added. This way if anyone is like, what were we doing here again or what was that other thing we were supposed to do for soandso, it can be found easier than searching through miles of posts.
