Twocents_XH allows your visitors to add their two cents. ;) You can use it as a general commenting possibility on multiple pages, or as a guestbook on a single page, or both, and it can be used as comments plugin for Realblog_XH. As markup language a minimal subset of HTML is optionally available, which can be entered with a simple WYSIWYG editor.
Optionally you can enable comment moderation (i.e. comments will not be published automatically), be notified about new comments via email, and you can add spam prevention by using a conforming CAPTCHA plugin.
The plugin requires CMSimple_XH ≥ 1.6 and PHP ≥ 5.1. It is released under GPLv3.
Twocents_XH is merely a draft—many features are missing yet, and what is there might change. It is a so called alpha version. Use with utmost caution!
