I can feel it in my bones. There is even going to be a solar eclipse on Christmas day. Here's my sales pitch. Many of us have a CD burner in our Linux systems, and the GNU Public License allows us to redistribute Linux freely. So, let's do it.
Some suggestions come quickly to mind.
For instance, if you happen to like one distribution over another, then perhaps that is where you should start. Go to that web site, be it Red Hat Caldera, or S.u. Buy them a boxed set or buy yourself a boxed set, and then start passing it around. For those friends not quite ready to dual boot or simply load up, might I humbly recommend that you provide them with a copy of one of the distributions I wrote about in the Linux for the Timid series. Find your favourite, make them a CD, and give them a copy of the article.
