Programming :: Read Multiple Input With Bash?

As I'm starting to learn bash scripting I'm trying to automatize some tasks I usually perform. I have a notification mail I need to send several times a day. It has this structure:

Quote:

Dear user,
blah blah blah blah

You need to contact the following people:

[code]...

To replace "user", I found this:

Code:

read -p "Please enter username: " username
echo "Dear $username,"

Which probe to be very useful with other simple notifications like this. But I don't know how to manage the email addresses as they are usually more than one and could vary from 1 to 10. They should appear one above the other. I found this: "Here is a little work around. The only thing the user needs to do is hit enter without anything else on a line and it will close out"

Code:

#!/usr/bin/ksh
word=a
until [[ $word = "" ]];do

[code]....

I tried to use it and modify for my needs but I failed, I don't realize yet how can I use it. If possible, I would like to use the until loop like the above example just for learning purposes but any other form will be accepted as well.
