Most of the time I'm organised, punctual and able to keep on top of all projects and tasks I have on the go. But lately I've found my current "system" is not working and I need a more efficent way to manage my workload.

I'm an I.S Support person working for a LARGE NZ company, I'm the sole support person in NZ and liase with our Australian support at least every other day. At any given time I could have 5-7 projects on that go at once, and (currently) as many as 25-30 active tasks at once. Some of those tasks are related to projects and some are independant stand-alone tasks that in their own right might be considered mini-projects.

My current means of managing this workload is Everynote, for the most part its been great and has fulfilled my needs. But more and more I'm finding myself looking for something bigger and better.

I'm not necessarily looking for a Project Management suit as I don't feel my 'projects' are large enough to warrent being handled in such a way. I'm more looking for a suit that will allow me to organise/group my tasks based on 'project', and also support my individual tasks in the same efficent way. I would need to be able to collate and group related materials (screenshots, word docs, excel docs) for each project or individual task.

The other requirement is that this be an online service, or at minimum sync all data online as I have a need to access this information between computers / locations. Also the ability to provide a shared link to guests giving them the ability to view information, and possibly also contribute.

Any and all suggestions would be welcome.
