Discord should be a fast reporting lane, not the source of truth. Launch it only with pinned rules for screenshots, source URLs, event timestamps and no-copy policy.
Create channels for weather, stock, corrections and moderator review.
Require evidence before any report becomes data.
Route accepted reports into the review queue and changelog.
GitHub issue intake
Because this site is statically exported, a public GitHub issue template is the cleanest first backend. The repository now includes .github/ISSUE_TEMPLATE/data-correction.yml, and the correction form creates report text that can be pasted into an issue. The email draft uses support@growa-garden2.wiki as the intended domain mailbox; configure it before relying on email intake.
