Alternatively, if everyone prefers, I can roll when the situation arises and then post the roll as I describe the result, but that doesn't let you spend any points.You can roll a live die at your house or use the play@ysdc dice roller (or any other online roller) and just reply with the result. I trust you.
Also, if you post that you're trying something that will probably require a roll - leaping from the moving train (Athletics), sneaking down the dark corridor (Stealth), picking a lock (Locksmith), following a guy (Shadowing) - you can post the roll in advance.
