you can use a
ProfileProvider

( with one implmentation being the SqlProfileProvider class )

to add some custom info about a User.

(Height, Weight, EyeColor as an example)

Is there a way to add custom information to the Application (s) ?

The reason I'm asking is I'd like to have a either an Active (bool/bit)
flag, or a daterange
( StartApplicationDate and EndApplicationDate )

so I can setup my applications, but have them active or automatically be
enabled/disabled on the date.

I"m trying to find the intelligent non-hacky way to implement this feature,
instead of hacking up the default membership provider stuff.

Thanks for any hints.

   <profile defaultProvider="SqlProvider">
     <providers>
       <clear />
       <add name="SqlProvider"
         type="System.Web.Profile.SqlProfileProvider"
         connectionStringName="SqlServices"
         applicationName="SampleApplication"
         description="SqlProfileProvider for SampleApplication" />
     </providers>

     <properties>
       <add name="Height" />
       <add name="Weight" />
       <add name="EyeColor" />
     </properties>
   </profile>
