First post so hello everyone. I have a mac mini running Lion 10.7.4 and I am thinking about upgrading to Lion server. One main reason, is to set up accounts for me and my girl friend as we both have macbook pros from work and don't want to store personal data on them. I have been reading up on how to set up the server etc but 99% mention that you NEED a static IP, is this really needed? I have Sky and they do not provide static IP! Thanks for any help.
