Hello Courage, Thank you for contacting me in relation to learning how to contribute to Wikipedia. Kindly create an account here to get started. Then proceed to this page to start on how to subscribe to the mailing list. That way you can send your queries and the community can support you when you have editing difficulties. You mentioned you cannot attend the 2nd March training so the best way is to use these help articles or simply seek help from me or the mailing list.
Regards,Sandister Tei ---
