Voting by any method other than the web-based process described here will invalidate your vote. o Failure to follow these instructions will result in your vote being discarded as an invalid vote. o Not voting on a letter ballot series or sending an invalid vote can affect your voting privileges. o The draft is password protected in accordance with IEEE 802 Policies and Procedures.
