Here are a couple of my suggestions;

Now Andrew if we could seriously look at the search function within Dolphin it would be most appreciated. Currently this function does not work very well if at all. Please correct me here if I am wrong. This is such an integral part of networking, why we would not spend more time refining it I cannot understand.

Secondly, any way we can incorporate the ability to choose between using username or First and Last name or both. Admin should have ability to decide see more on the onset which way to set it up. Either one or the other or both.

Lastly, remove the interdependence between modules. That would solve a lot of issues.
