BuddyPress.org

@callumoberholzer BuddyPress profiles have been getting more and more robust.

Member search is something BuddyPress is not very good at though. Plugins such as BP Profile Search offer a partial solution. So if you feel search function is too limited, do feel free to contribute code to make BuddyPress better. Any help is always welcome.

Hi @callumoberholzer

BuddyPress allows you to have:

member profiles
an advanced member search (through the BP Profile Search plugin)
private messaging

So it looks like your requirements are covered. My advice would be to set up a test install and try out all of the features to see if they meet your requirements.
