+# Contact Admin update screenshots — 10/18/2026
+
+Captured with [phpbb-release-tools](https://github.com/phpbbmodders/phpbb-release-tools)’ `phpbb-test-board/screenshots.py` on a disposable phpBB 3.3.19 board, with the board’s email turned off.
+
+## Delivery settings
+
+The contact method choices are now drawn by the extension’s own template; phpBB 4.0 removed the helper they used. The note under “Contact method” now appears when the board cannot send email.

+
+## Guest form with the username check and privacy policy box
+
+With “Check Username” on, guests now see the board’s username rules under “Your name”. The privacy policy box works with its label.

+
+## A guest’s message posted by the contact bot
+
+Messages from guests are labelled “Guest User” again when the contact bot posts them.
