I am able to implement GTD using Outlook locally very well and it works great. My latest problem is that I now partner with a colleague on many projects and need a centrally located GTD solution that both of us can use from separate locations to track all of our projects, calendars, etc.
Does anybody have any suggestions for solutions that work with the GTD system well? Most likely these will have to be web-based. Free/open-source would be great but we're willing to pay for a decent product/service if it exists.
I'm open to any ideas so please share.
Thanks so much for your time!
