2013 - Getting Task assignment emails to work SOLUTION

Question

The option for having SP send emails when a task is assign keeps being removed and added back by Microsoft - currently its gone.
You can get it back by iterating through the site and enabling the
EnableAssignToEmail
This used to work but not anymore:
$web = Get-SPWeb "https://Your Site.com/"
$list = $web.Lists.TryGetList("Tasks")
$list.EnableAssignToEmail = $true
$list.Update()
You have to do this after each Task List you create
It only took me 3 months to figure this out...
Add-PSSnapin Microsoft.Sharepoint.Powershell
[Microsoft.SharePoint.SPSecurity]::RunWithElevatedPrivileges({
$webApplicationURL = "https://Name of your Site/"
$webApp = Get-SPWebApplication $webApplicationURL
if($webApp -ne $null)
  Write-Host "Web Application : " + $webApp.Name
  foreach($siteColl in $webApp.Sites)
     if($siteColl -ne $null)
         Write-Host "Site Collection : " + $siteColl.Url
         foreach($subWeb in $siteColl.AllWebs)
            if($subWeb -ne $null)
                #Print each Subsite
                #Write-Host $subWeb.Url
                 Write-Host "Site: " + $subWeb
                    $site=Get-SPWeb $subWeb.Url
                    # $web=$site.OpenWeb()
                    $lists=$site.Lists
                    if($lists -ne $null)
                        foreach ($list in $lists)
                            if ($list.BaseTemplate -like "Task*")
                                write-host "Attempting to update: " + $list.title
                                $list.EnableAssignToEmail =$true
                                $list.Update()
                 $subWeb.Dispose()
           else
                Echo $subWeb "does not exist"
            $siteColl.Dispose()
     else
            Echo $siteColl "does not exist"
} else
     {       Echo $webApplicationURL "does not exist, check the WebApplication name"
     }Remove-PsSnapin Microsoft.SharePoint.PowerShell
Echo Finish
