While it is best to only participate in one live draft at a time, you can enter multiple drafts simultaneously.

Additionally, while we strongly suggest that each manager participating in a live draft uses his/her own computer, it is possible to have multiple managers drafting on the same computer.

In order for multiple managers to draft at the same time, the first user would log in, launch the live draft, and then log out of Yahoo! while keeping the draft window open. The second user (and any subsequent users) would then log in and launch their own draft window.
