As an admin, you should be able to edit the message automatically left at Mediawiki:Welcome-message-wall-user and Mediawiki:Welcome-message-wall-anon for your wiki if you want to have custom messages. If you mean you want to edit the message after it is left on your wall, you can only do that as an admin. But you can respond to it or remove it if needed.
