Pocoo is a bulletin board software (a.k.a. message board). It provides an advanced plugin system with a component architecture which allows other developers to modify Pocoo to their liking without the need to touch existing source code. Because it uses SQLAlchemy, it is possible to use either MySQL, SQLite, Oracle, or Postgres as the storage backend.
Active Image Viewer is an image viewer that provides a very efficient way to display multiple images within a small area. Thumbnails are automatically generated and displayed (removing the need to create smaller versions of images). When a visitor clicks a thumbnail, the full size image is displayed within the current page. Each full size image may have a link attached to it which can be set to either open in the current browser window or a new window.
CalendarTechnique is a Web-based calendaring and scheduling application.
