[Mediawiki-l] Re: Form Pointers Wanted

I'd like to make pages that accept form input, go off and query MySQL, and display results. For example, voting on proposals, maintaining a distributed book/video library, or time sheet logging. It would be really cool to make this an extension, so it could be configured and embedded in any page -- especially if it could still function if the page is protected from editing. I suppose the alternative is a Special page. Having played with some extensions, I'm having trouble conceptualizing how form-based interaction would work. What would the form target page be? I suppose it could be the same page, branching off the existence of GET or POST data to figure out if the form was being sent or received. I'm not asking anyone to solve the problem for me -- just post some URLs of things that are similar to what I'm looking for. I once came across a voting system, but have been unable to find it (or anything similar) on Meta. Thanks in advance for any advice offered!
