Thanks for the feedback so far. What I plan to do now is to work on detailing the client's requiremnets a bit better and also get the team to start to look at the features of OACS that I feel will be most useful. I think we will be almost certainly be looking at expanding functionality in some areas. I would like to discuss the issues that come up openly with the community, and there does seem to be some interest, so I think that's the way to go. "Watch this space" as they say...
