I am playing around with Amazons EC2 new free tier plan and noticed the default ubuntu install comes with a user ubuntu that is preconfigured to work with your key you are provided from AWS. One thing I would like to do is add a new user and remove the default "ubuntu" user. From my experience with other VPS (VMWare and Rackspace cloud) you only have root on your fresh install (tho that is with Red Hat and not Ubuntu).
Should I have any problems removed the default ubuntu user?
Or should I just not touch the user "ubuntu" and create a new user for my to login and do my work.
