One of the biggest issues in getting your organization into online work is the mental shift. It isn't just a matter of "doing what we already do, but do it virtually." This shift is one of 
- being clear about the process
- building steps backwards from your desired result
- intentionally simplifying what the group does
- building in feedback cycles.
Most people using collaboration, it seems to me, are doing one of these: running surveys, conducting ongoing discussions, holding online meetings or making a list of tasks. Nothing wrong with this -- but what we advocate is setting up an ongoing workspace, and doing several of these things in context within an organized environment. When you do this, you are more likely to involve your intended audience in meaningful work over time, because you will end up doing more than one mode in order to collaborate effectively. Your people will understand the context, and therefore can be more participative.
One of the largest benefits in working online is that the work is immediately archived -- that is, it is available to everyone, anytime they want to access it. People can refer back to what happened, and the process is transparent. But this also means you need to make it
- easy for them to find, and
- easy to understand in the context of other work that is taking place.
Have simple areas to contain different parts of the work, and show links to what is current. Have one place where the discussion about that work takes place, and make sure someone is actively "gardening" the discussion and the progression of tasks in your process.
