um, you'll have to download Java, which is very useful and doesn't affect your computer. We won't do a draft till late August, so between then and now, it would be good to familiarize yourself with ESPN fantasy and how everything works. they have mock drafts starting later this summer and i'll definitely be availabe to answer any questions you have..
if your company's a stickler about non-work related stuff, you could still be okay cause Java is a small program that will only show up when you enter the draft. I've drafted at work too lol, and your biggest worry is keeping the draft minimized when people are walking by
