maintaning extra user-specific data (profiles)

[R.A.M.]

Hello,
I am learning .NET (3.0). I am writing ASP.NET application and I need to
store some extra information (like default settings for each user.
In web.config I added:

<profile enabled="true">
<properties>

<add name="DefaultProject" type="string"/>

</properties>

</profile>


But I don't know how to maintain the data. In Website|ASP.NET Configuration
I don't see my properties.
Could you help me please?
