Need object oriented PHP code using MySQL backend to support unlimited thread comment system. Function should be identical to Yahoo comments with the addition of unlimited thread capability rather than Yahoo's parent/child limitation. Would use existing "Users" table to pull needed user information for each message buy user_id (screen name, avatar, location, etc.). Page would initally display parent comments and allow drill-down to child comments using AJAX. Ability to sort by newest, oldest, most replied - same as Yahoo. SQL elements should use Nested Set Model. UI is not important, but basic look and feel of Yahoo could be simple target. The use of existing scripting, classes, objects or code is fine as long as it's open source and freely distributable, as well as fully documented. See attached image for example. There is probably something like this out there, but I don't have the time to look for it.
