Forms collection

I am quite new to VB, so I apologise if I don't explain myself fully.

I am in the process of writing a program that will show a notification form in the bottom right corner of the user's screen. This form is displayed when a text file is created in a predefined directory, using the FileSystemWatcher. My question is regarding managing these notifications, as there maybe more than one, changes to existing ones and ones that need to stay on the screen and be updated. How can I create an instance of a form of class type notification and assign it a unique number/ID and add it to a collection?

I can currently display one form using , but I'm stuck when creating another and would like a way to manage these using some sort of collection.

Any help or advice would be much appreciated.
