I thought I better put some screenshots or MS Groove so you can get the idea how does it look it. It is very simple to use when you look at the GUI and very productive too. This product will be a de-facto everywhere very soon in the future. Everyone will be grooving either online or off-line; I like grooving myself and would like you to at least. You can always download a free trial version from Microsoft Office website for 60 days. Do the hands-on.
