Task Management Recommendations, pretty please: must be able to have multiple users

Hiya,

I work in a 3 person company. We have synced iCals, but the To Do list feature on iCal isn't... sophisticated enough for us.

We're looking for a To-Do list app, that:
- we all have access to view, edit, etc.
- we can sync with our iCals and iPhones
- gives you the option to add different levels of priority to a task
- gives you the option to assign tasks to a person
- gives you different view options (i.e. 'show all high priority tasks only')

I'm guessing my best bet is to just go with an online app (such as Basecamp or even Remember the Milk), but being new to the Mac world, wanted to check I'm not missing a trick?

We use Entourage for our mail, rather than Mail, btw.

Thanks for the help in advance!

Why not just use Outlook?

Thanks for the reply, but slightly confused.

Whilst we do have a Microsoft Office Suite on our company Macs, it doesn't include Outlook: plus, my superiors are loathe to move away from Entourage for our email, so it would be a hard sell.

Surely there's a Mac app that can do the job, without having to buy a Microsoft additional?

Set up a gmail account that is shared. No need to do anything to Entourage or Outlook.
