[2008] Saving More Than 1 Line Of Data To A Text File?

Basically iv got a form, and the fields are

"Full Name":
"Amount Contributed in �":

below the form i have a button that saves the data to a text file called 'mailinglist.txt'

So i enter the data into the fields and click the button like as follows:

Full Name: John Smith
Amount Contribted in �: 40

However..... when i go view the text file it displays John smith40, which i want a space between the name and the numeral.

Also as i want a maximum of 5 people added to the mailing list, i would like a function that lets me somehow "adds" an extra 4 people to the text file without overwriting the 1st name, and uses the same "current" form displayed to the user.

Here is the code as follows:

Public Class Form2
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged

[Code]....
