Hi! I'm looking for an addon that would redirect users to a page based on certain keywords in their thread/post. Essentially, I'd like this to work in a similar fashion to the way Tumblr does - when you search for the tag 'Suicide' it shows a message with some info: The basic function I'm looking for would be to scan content submitted by users for certain keywords (suicide, etc.) before it's made public and automatically show them a page similar to the one above before they are allowed to submit their post. Is this possible at all?
