Assistance with prompting for users and then adding them to a command in PowerShell

Question

I'm trying to create a very simple script to add members to a Distribution Group. I want to do something like I added below. I would like to prompt for user1, user2, user3, etc.. until I have no more users to add instead of manually typing out
the command below. Each time there will be a different number of users to be added. I do not want to do a csv import since it creates extra work when sometimes I only need to add 2-3 users. I find using a csv works great but takes too long when
I only have a few to add. I would like a way to just keep typing user aliases until I have no more and then hit enter and have it take my entries and enter them into the command below or some other similar command. I would like everything embedded
in the ps1 file with no other files to deal with. Any help will be appreciated. Thank you in advance. 
$DLName = Read-Host "Enter the name of the DL that members will be added to."
"user1","user2","user3" | Add-DistributionGroupMember -Identity $DLName

Answer 1

Here's another option:
$DLName = Read-Host 'Enter the name of the DL that members will be added to.'
((Read-Host 'Member List, separated by commas').Split(',')) | ForEach { Add-DistributionGroupMember -Identity $DLName -Member $_.Trim() }
