One of our parents, Silvia Terziotti, just created a closed Facebook group for Exploris parents to post questions, answers, and ideas.
If you want to join, click this link and ask to be added. Silvia will approve you and you’ll be good to go.

Once you’re a member, you can post and you can invite others to join.
FYI, this group is a closed group by and for Exploris parents. Teachers and staff may join, but questions you post will not be officially answered by Exploris staff.
Exploris PTO 
Not that I know of. People are connecting and asking questions in the comment sections of Blog posts, but other than that I haven’t heard of anything.
I do know that a couple of elementary parents will be announcing efforts to form play groups shortly, so that would be one way to connect.
You are also always welcome to attend our PTO meetings. After the official meeting, I plan to have “Social Time” for parents to discuss issues and ask questions that we don’t have time for during the 45 minute meeting.
