I’ve been making a few tweaks to the Agreement System we have on nachi.org. We’ve had a few people who accidentally copied spaces into the email address, which would cause a search to fail - that’s fixed! And I’ve made the error/success messages match the style used now on nachi.org.

Let me know if you need other tweaks! Thanks for the suggestions.
