If a new instance of the form was created, the I can see setting it to nothing. But, in the case of a single instance, unloading it is sufficient.
When multiple instance of the same form are in place..setting each instance to nothing after unloading makes it sure that the object doesn't take the memory anylonger...
One good and bad thing about the unload function is that any public variables on that form will still be accessible after it has been unloaded.
Therefore, if you load a form modally, then unload it and want to know something about the form, providing you store it in a public variable on the form it will still be available to the calling procedure until you set the form = nothing.
eg;
Load MyPopUp
MyPopUp.Show 1
If MyPopUp.PublicVar = "This" then DoSomething
Set MyPopup = Nothing
