From the IEEE Region 8 Director’s mail to members:
Less than 15% of the IEEE members with voting rights have voted so far – worldwide!
Region 8 (Europe, Africa, Middle East) has almost 60000 voting members. In recent past, even Presidents have been elected with fewer than 20000 votes, and some Directors with significantly less. Also, some officers have been elected with a very small vote difference. Therefore, your vote is very important!
Dear Director, do not ask me to vote. Find out why I am not voting, even though I am a member and eliminate the problem. Dear candidate, this is your challenge too: Increase the number of voters (and their level of engagement) during your stay in office.
