What it means: Runs while extra fields are rendered on the network signup form. It is a form setup event, not a completed signup.

How to use it
- Use this event only on a WordPress Multisite network; it is not available on a standard single-site installation.
- Check the available event data and confirm whether the event represents a setup stage, a completed change, or a removal operation.
- Test on a staging network before enabling workflows that modify sites, users, or access.
Important note
Multisite hooks can fire as part of internal network processing. Verify the timing and payload in your own network before relying on the trigger for business-critical automation.
