I'm a bit new to user controls, and am taking on an advanced task: creating the necessary cms controls and macros to achive the same level of member management that is available on the umbraco membership system - this time for asp.net membership and profile providers

I've gone as far as the following wiki how-to article can take me:

http://our.umbraco.org/wiki/how-tos/membership-providers/how-to-integrate-aspnet-membership-control-with-umbraco

So now I have umbraco accessing the database for members and roles. It's great that I can create new members, but unfortunately that's about it.

Where do I go from there? I'm hoping there is a way I can just modify the existing umbraco user controls to work on asp.net profile providers, but if I have to start from scratch I'm up for it.

Just need some advice from anyone who's been there and implemented this?

Even the simplest thing has me stuck: how do I enable password changing for asp.net members??
