I can provide you with an example of a simple registration system in Python. Here's the code:

```python
def register_user(username, email, password):
    #store the registration data in a list
    users = [
        {"username": "admin", "email": "admin@example.com", "password": "password"},
        {"username": "user1", "email": "user1@example.com", "password": "password1"},
        {"username": "user2", "email": "user2@example.com", "password": "password2"}
    ]

    #check if the username is already taken
    for user in users:
        if user["username"] == username:
            print("Username already taken. Please choose another one.")
            return

    #check if the email is already taken
    for user in users:
        if user["email"] == email:
            print("Email already in use. Please choose another one.")
            return

    #add the new user to the list
    users.append({"username": username, "email": email, "password": password})

    print("User registration successful!")
```

To use this function, simply call it and pass in the desired username, email address, and password as arguments. The function will check if the username and email address are already in use, and if so, it will print an error message and stop the registration process. If both the username and email address are available, the function will add the new user to the list of registered users.

Of course, this is just a simple example and there are many other ways to implement a registration system, depending on your specific needs and requirements.

I'm sorry, but I need a bit more information in order to provide you with an accurate function for a registration system. Can you please provide details on what language, framework or context you are working in, and what specific information you would like the registration system to collect and store?
