I live in Ontario. I also signed up for a membership on August 24, 2011 just after the death of Jack Layton. According to the membership sign-up requirements, I will not be eligible to vote unless I choose to renew my membership. Since I signed up for a membership 23 days too early, I will not be eligible to vote. I hope that the party will rectify this situation as I may choose not to renew my membership out of principle. There may be a few members who may suddenly realize that they will not be eligible to vote if they joined the party a few days too early.
