I've never taken part in a live draft online. What is that like? What are the time limit settings?
Imagine intense pressure ... the kind of pressure that makes you want to open a window and scream, "I can't take it anymore!
A live online draft is nothing like that.
I don't know the time limits, but as I recall you get about 1 minute once it is your turn to pick, but it seems more like 10 seconds.
I recommend you edit your pre-draft rankings in case you are unable to participate -- for whatever reason, including technical difficulties -- in which case the computer will auto pick for you based on your rankings.
I also recommend you check the league settings to see how you can score points. (e.g., throwing TDs are worth 4 points for your QB, receiving TD are worth 6 points for your WR, TE or RB, etc.)
