One form, read by a person. Pick what it is about and write it here — no mail client, no account.
There is no support queue and no ticket number — it is a small project, so replies come from the person who made the thing you are writing about.
What is it about?
Something ambiguous, or two of you reading a rule differently. Say which variant you were playing; most disagreements turn out to be Perfect Match versus One Good Match.
Before you write
Most rules questions are already answered in the FAQ or on the rules page, and if you are writing about the game the press kit has the fact sheet, the copy and the art ready to reproduce. None of that is a brush-off — it is just faster than waiting for a reply.
If you would rather use your own mail client, the address is matthewelisephparker@gmail.com.
Next: the FAQ, about the game, or just play it.
