szouljahboii312, the most painless way to explore is to use VirtualBox and run "virtual machines" from within Windows.
You don't really need any seminars for this. Just download the ISO and install on a virtual machine. Whatever knowledge you have about how to install Windows will carry over, more or less.
You'll probably go through a stage of "distro hopping" where you try all sorts of distros, but eventually you should be able to decide which "brand" works for you.
Has anyone installed Ubuntu 11.04 yet? Any thoughts on choosing this over 10.04 LTS for a home server?
