The security architecture is the only problem as it's a little bit complex and too torturous at times. So it could be improved a little bit, but it is regarded as a very good system in Australia. It's probably overly subscribed. Also, what's missing is what people would like, which is basically online collaboration. That's a problem. But it has so many other things to offer that SharePoint, I'm sure, will not have. So, that will be an interesting issue to come up. It's not very good at providing stable and robust add-ins to Microsoft. That's a bit of a problem with Content Manager. They're kind of very volatile. So, that's been definitely something that could be improved.
