PullCount is a one-person fan project. There is no support team — just "Hyphonatedx". That said, messages do get read and bugs do get fixed, so don't hesitate to reach out.
The best way to get in touch is by email: contact@pullcount.gg
Response time is typically within a few days. During an active Race to World First things get busy, so it might be a little longer — but every message gets a reply eventually.
