How to change a line of text to a comma delimited string?

Hi,

Is there a one-liner that I can use to change a line of text into a comma delimited string?

For example, convert

Code:
user1
user2
user3
user4

to

Code:
user1,user2,user3,user4

Currently using while read x, although got the extra comma at the end that I have to remove manually.

Please advise. Thanks
