I'm happy to hear that you've been using the snake and it's been doing it's job for you. As for your problems.
Have you already changed the root password? If so, then that part is completed.
As for the snake, you can create a new user with administrator priviledges or you can just change the password for your existing user.
If you log into the mailwatch interface and go to tools/links, select user management. You'll then be taken into another window that lists all your created users. From there, you can add, delete or edit the user profiles accordingly. I would just change the password on the current user.
Hope this helps.
