At first glance this may look like one of those to do lists. It is however much more powerful, with all sorts of extra features that make it very useful for staff and students (especially students!)

30boxes is a calendar tool that has the extra feature of allowing you to track headlines from RSS Web feeds

TeamCowboy is for students or tutors who manage student sports teams. Track your roster, set up game schedule, game scores, payment for equipment, etc.

Engrade is a suite of tools that acts as a gradebook for courses, as well as a communication vehicle. It seems aimed at schools as it allows parents to participate. However college students and tutors could benefit. Grades and scores can be weighted and listed by letter or number. Administrators can oversee educators' classes.

An earnest-looking project by the good people at Tufts. They ought to know what they're doing and have added several useful features to a traditional mind-mapping tool.

Double-clicking works for creation and editing anywhere. Drag-and-dropping works for reorganising, marking, map-shot, and adding attachments. Explode your ideas without any interruption. Write in-line notes and record audio notes in your meeting minutes. You can even search your topic in Google and drag images back without leaving the working window.

Mindmaps can help you decide what topics to study, as well as provide an upfront visual cue of what you already know and thus don't need to study. Mindomo has an interface and feature set that rivals even free standalone mindmapping applications such as Freemind. Maps are shareable but require you to register and login to save them.

Very new and very, very interesting. Billed as a project management tool, the nice interface features a calendar, a place to write tasks and a list of the people in your team. Dragging items from one place to another produces target end dates or adds them to others' lists. Substitute assignment for project and student for solleagues, class for team and you'l get excited too. Oh, there's also a live chat facility too! Amazing. All on-line. No download.

Writeboards are shareable, web based text documents that let you save every edit, roll back any version and easily compare changes. Use Writeboard to write solo or collaborate with others, either within your college or wider, or to work with students on assignments. Writeboards can also link into the BackPack tasks and to-do organiser site.

Freemind is an open source mind mapping tool that is very easy to pick up and use, some say. Some heavyweight brains behind this project. As it is written in Java it will require a download of the latest Java runtime package.
