On August 10th, I sent a private message to a Project Leader from their profile page. (I have my copy in my inbox) I had a question on whether a person should be considered an Abolitionist. I still haven't received any response.
Last Friday, I sent a private message to a different Project Leader with questions about a state category. I haven't received a response.
Both Project Leaders are active here on the forum which leaves me to wonder if my messages aren't really being sent or are being sent into Spam.
