Hi RafikI have tried casting my ballot and on submitting, I got a response that it is 'invalid ballot'. Maybe the problem still exists.

Hi everyone,

The voting period just started and those who checked-in should receive the ballot from this mail address [log in to unmask] . There was minor issue and it is fixed now.
Below, you will find some  explanation on how the vote would work :- For NCSG chair position:  you should select 1 candidate only- For GNSO you can select up to 3 candidates. if you select more than 3 options your vote will be invalid.- In each list (Chair, GNSO councillors), you will also find the "none of the above" option . - You can change your vote till the deadline 14th September 23:59UTC, only the last selection will be counted.- You can change your vote by clicking in the same link you received at the address [log in to unmask] You will receive several reminders about casting you ballot. if you voted already you don't need to do it again. if you do, only the last selection will be counted. - You will find in the ballot the weight of your vote: 1 for individual , 2 for small organization and 4 for large organizations.
please feel free to ask me any questions to clarify the process.
Best,
Rafik
