Event Metrics imposes a per-wiki maximum for how many pages, files (on Commons) or items (on wikidata) can be tracked. The maximum is 50,000 per wiki. To let users know about this limit, we will add:
- **A note on the Event Settings page** next to or on top of the field where users add wikis. !!@Prtksxna please provide a design.!!
- **A [?] link **to the [[ https://meta.wikimedia.org/wiki/Event_Metrics | Help page ]] location where this is discussed in full. !![precise Anchor link to correct help page section to come]!!
This will let users planning very large events (which happens on Commons and Wikidata, especially) know that they need to divide their event up into separate events, e.g., by categories.
===Suggested language for the note
- **Per-wiki maximum: **the system can track up to 50,000 pages, files or items on each wiki. [? icon hover text: learn how to work with this maximum]
