Bring me the question as it currently exists.
You do not need a finished brief or a neatly classified problem.
A useful first note says what is happening, who is involved, what decision or deadline is approaching, and what kind of help might be useful.
Introductions are welcome. So are half-formed questions. We read everything and (usually) respond within three business days.

Have a code word?
Put it in the subject line and tell me two things: the question, and the decision riding on it. That is all I need to come ready.
I use the information you send to reply and to handle any resulting work. See the Privacy page for details.
What helps me respond well
You do not need to answer every question below. These are simply the details that tend to make a first conversation more useful.
- What is happening — the question, concern, or opportunity as you currently understand it.
- Who is involved — the people, teams, organisations, or suppliers whose perspectives matter.
- What is approaching — a decision, deadline, meeting, obligation, or other reason the question matters now.
- What might help — continuing advice, focused analysis, a briefing, a working session, or simply an independent first read.
Mention any timetable, procurement constraint, or confidentiality requirement that would be useful to know early.
Standard MSA, mutual NDA, and procurement documentation are available on request.
Press and media
For interview requests, commentary, or background briefings, email press@propertools.be. Please include your outlet, deadline, and the angle you are pursuing.
For background on the 2036–2038 timestamp rollovers, the Epochalypse Project FAQ is a useful starting point. Related work is also under way through the FIRST Time Security SIG and ITU-T .
For a time-sensitive request, put the deadline in the subject line.
