Contact
Writing is the easiest start. If talking is easier, ask for a short call and suggest a weekday time that could work for you.
Only include this if phone is a useful backup. Email is enough.
A rough version is useful: what exists, who uses it, what feels risky or blocked, and what would help soon.
Preferred call time request
Choose a weekday at least 48 hours from now. I will reply by email to confirm or suggest another time.
Timezone included with your request: UTC
