Does your PTO have an email address? If so, how exactly do you use it, and how do you administer it? What are your policies/guidelines/procedures?
I have just set one up for our PTO, with a mailing list to all the parents who gave the PTO their website address for inclusion in the school directory. In our paper newsletter, we let the parents know that we would be doing this soon, and they could opt out if they wanted to. Other parents not in the directory could opt IN if they wanted to.
Now the question is: what should we use it for? My ideas thus far: meeting agendas & reminders - day before, meeting minutes or summary, reminders of events & activities - day before, call to action items like important school board meeting or letter writing campaign to the state, emergency need for additional volunteers, save-the-date announcements (mark your calendars...details to follow later).
