That is the only address on this site. There is no contact form — which avoids handling data nobody needs to collect.
What belongs in that inbox
- A correction. A licence that changed, a repository that moved, a project that got archived, a wrong figure in an entry. The gemshelf entries cite their sources precisely so that this kind of error stays verifiable — and therefore fixable.
- A tool suggestion. A free, self-hostable project worth an entry. A link to the repository is enough.
- A report. Content that causes a problem, a copyright issue, a takedown request.
- A GDPR request. Access, rectification or erasure of data concerning you — see the privacy policy.
- A business enquiry. Z29K is a consulting and development company; this site is its public technical watch.
