You can make changes to your membership for the next season. Your invoice will be adjusted to reflect the changes. If the invoice amounts change, your balance will reflect the addition or subtraction (remember, a negative number is a credit balance.)
If you want to make changes for this current season, email Phil at firstname.lastname@example.org. This will insure that the right pro-rated adjustments are made to your current invoice. If you have questions, call him at 612-308-2664.
