I have assigned the weekday 8am masses to servers in the same grade. This may be useful as an easy 'buddy reminder', the day prior. If you need to trade an 8am weekday mass -- it's ok to trade with ANY server in ANY grade!!
Unlike the summer months, I did not solicit server availability for the school months. Hopefully, with no vacations during the school year, it should be easier to trade as conflicts arise.
Thanks for the family support for alter serving. Having had two servers of our own in the past, I appreciate the commitment by all.
