Hello Kevin, I have created a wiki home page for you (wiki.centos.org/KevinBulgrien) and would suggest that you use it to lay out your proposed changes in a draft form. When done, just ask on this list for a review and comments and then your contribution(s) can be merged. I have appended a copy of the /TipsAndTricks/VncHeadlessInstall page to your home page so that you have something to work with.
