On Purchase to another membergroup

[chep]

On purchase a user can be moved to another member group and the membergroup can expire after a period of time.
How does this work? I cannot figure out how I would go about implementing this?

Thank you

When you add a product there is a settings called
Group to Move to:      
Group Expire in days:

I knew I was a retard 

I see it now.

So ? ... The group will expire in that days ? ... Or just the MEMBER will be out of that group ?

Thanks !

Just the member will be out of the group.
