Sharing a Generic Collection

Seems quiet in here, but I will throw this out here anyway.
I have a Windows Forms C# program (using .NET ver 2) that has several heterogeneous threads (BackgroundWorker) that need to access a common Generic Collection that is a private property in the Form collection. Example:
BackgroundWorker 1 - Reads POP3 e-mails and places them in the collection.
BackgroundWorker 2 - Scans the collection for work to do.
BackgroundWorker 3 - Scan the collection and report on work done.
BackgroundWorker 4 - Scan the collection and handle trapped exceptions and housekeeping.
Now, when I create each thread, I have this in the BackgroundWorker class...
public MyCollectionClass MyCollection.
My creating code does...
newBackgroundWorker.MyCollection = GlobalCollection;
Now, I thought that when I did this, I was assigning a reference into the class, not copying the collection. It seems to be copying the entire collection, not pointing the property in the BackgroundWorker to the global collection.
Thoughts? How DO I get several threads like this to share a collection?
TIA
-Ken
