Contact
CoreConcept is a small educational project. We read every message — corrections and factual reports get the highest priority.
The best way to reach us is email. Include a short subject line and, for article issues, the full URL of the page.
Example subjects: Correction: /blog/cap-theorem-explained, Topic request: backpressure patterns, or Privacy question.
What to write about
- Factual errors, outdated product surfaces, or misleading diagrams
- Broken links, typos, or accessibility problems on a page
- Topics you want covered next (and why they matter to you)
- Permission to cite, translate, or reuse CoreConcept materials
- Partnership or sponsorship ideas that do not change editorial recommendations
- Privacy, cookies, or advertising questions (see also our privacy policy)
How to report a content error well
Helpful reports usually include:
- The page URL
- The incorrect sentence, diagram label, or code sample
- What you believe is correct, with a source link if possible
- The date you checked (especially for product UIs that change)
We update articles when claims go stale and note material revisions in the changelog.
Response time
We aim to reply within a few business days. Simple corrections are often faster. Complex partnership or legal requests may take longer because a person — not an autoresponder — reviews them.
We do not sell personal contact lists. Emails you send are used only to respond to your request and improve the site.
