Contact

One address, read by the people who make the site. What to send us, and what we cannot do for you.

Effective October 4, 2026 Applies to Omni Mundi Compendium

Email

Everything — corrections, privacy requests, reuse, broken links — goes to one address. There is no phone line and no postal address: this is an online-only publication and email is the contact channel.

editor@omc.center

If you are writing about a specific page, please include its URL, and if you are reporting an error, the source that shows it (usa.gov and agency sites are the most useful). It makes the difference between a correction taking days and taking weeks.

What we welcome

  • Factual corrections, out-of-date rules, or a figure that no longer matches the source.
  • A citation that does not open, or that does not support the sentence it is attached to.
  • Broken links, missing pages, or anything on the site that does not work as it should.
  • Privacy requests — access, deletion, or a question about anything in the privacy policy.
  • Permission to republish, translate or quote at length.

We read every message. Because a correction has to be verified against the primary source before the text changes, replies can take a few days; that delay is the checking, not neglect.

What we cannot do

This is a small independent publication, and it is not a professional service. We cannot:

  • Review your individual legal, insurance, financial or medical situation, or tell you what to do about it.
  • Recommend a lawyer, an attorney, an insurer, a policy, a fund or a product.
  • Act as your representative, agent or adviser, or correspond on your behalf with an agency or a company.
  • Provide an opinion, a letter, or a document you can file or submit anywhere.
  • Take on new work, quote for it, or refer you to somebody who will.

Emails asking for case-specific advice will not get an answer that is useful to you — not because we are being coy, but because doing it properly requires a licensed professional who knows your facts, and doing it improperly is worse than not doing it at all.

Where to go instead, for actual help

For a real situation, these are the channels that exist for it. We keep a fuller, categorised list of official U.S. resources on the network's resources page.

  • General government services and benefits: USA.gov.
  • Legal help and lawyer referral: your state or local bar association's referral service, which USA.gov links to; legal aid is available on income grounds in every state.
  • Insurance questions or a denied claim: your state insurance department — the NAIC keeps the directory.
  • Health coverage: HealthCare.gov for marketplace plans, Medicare.gov or 1-800-MEDICARE for Medicare.
  • Tax questions: IRS.gov.
  • Consumer and financial complaints: the CFPB and the FTC.
  • A mental health crisis, in the United States: call or text 988 for the Suicide and Crisis Lifeline.

Privacy of what you send

We use what you send only to deal with your message. We do not add you to a mailing list, and there is no mailing list. What we hold about you is your email and what you wrote, and it is deleted on request — see the privacy policy for the detail.

The rest of the fine print

All four pages apply to every site in the network
