help me
 

how to add so many users at the same time.

please use better titles than "help me". your title should reflect the issues you are having, to help others know if their knowledge may be of use.

Please make your question a little clearer so that others can gather some info.
I am new here and have learned that taking a scientific approach in posing a question works very well.
State clearly your problems,or what you would like to do and all kinds of people will be glad to help you.
Sorry i am not at the helping level yet.:)
