QAMaker lets you create a searchable list of questions and answers for your website with a simple HTML form. You can add entries, and let viewers see the full list of questions or just search for what they want. Heavily based on VocabSearch, it does not now let you delete questions/answers from the file: you must do that by hand. Still, it makes a nice list of frequently asked questions if such a thing is useful for your site. This is what Scripts for Educators uses for our FAQ.
