You can access the login name using several methods.

Via Windows API (preferred and most reliable method)

Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long

Public Sub Main()
  Dim sUser As String
  Dim lpBuff As String * 1024

  'Get the Login User Name
  GetUserName lpBuff, Len(lpBuff)
  sUser = Left$(lpBuff, (InStr(1, lpBuff, vbNullChar)) - 1)
    
  MsgBox "Login User: " & sUser
    
End Sub

Via Environment Variables:

Sub Main()
  Dim sUser As String
  sUser = VBA.Environ("USERNAME")
  MsgBox "Login User: " & sUser
End Sub

is there any macro that allows a random extraction from a particular kind of distribution (normal, binomial, etc) and put that number in a cell so it could be changed pressing F9?
thanks
