Powershell Array - arrays

Question

I’m trying to get multiple users first and last name to be converted into a format: first initial+ last name while using a GUI input box. My code is wrong and it keeps the first array letter and won’t remove it to allow the other inputs to do the same task. I tried the Remove to help remove the fixed size array. Didn’t work. I read that I must create another array to remove from the first array. This is where I’m stuck. How do I make the second array delete the first entry while keeping the same variables if possible - I want to enter X number of names into the input box and run other other task for each user.
right now the results are the following:
jblank
jeric
jbob
Im trying to get
jblank,enewnew,bmo
help please. thank you

#initials
$In = $FName
$InRM = $In.Remove(1)
$unID = $InRM+$LName # intials done
$newID = #()
foreach ($u in $User)
{
if ($User -ne 0)
{
Write-Host "Remove [0] here or something like that eq to $unID again"
}
}

## Do more stuff here for each user ##

Do you think at something like that?
$User = "joe blank, eric newnew, bob mo"
#define arry for later
$SortUser = #()
#split users from textbox
$Users = #($User.Split(","))
#loop users
foreach($i in $Users){
if($i.Substring(0,1) -eq " "){
#remove space which make problems
$i = $i.Remove(0,1)
}
$Split = $i.Split(" ")
$First = $Split[0]
$Last = $Split[1]
$FirstLetter = $First.Remove(1,$First.Length - 1)
#Add all informations to object
$obj = New-Object PSCustomObject
$obj | Add-Member -type NoteProperty -name First -Value $First
$obj | Add-Member -type NoteProperty -name Last -Value $Last
$obj | Add-Member -type NoteProperty -name Username -Value "$FirstLetter.$Last"
#fill all objects in one array
$SortUser += $obj
}
$SortUser
Result:
First Last Username
----- ---- --------
joe blank j.blank
eric newnew e.newnew
bob mo b.mo
