Very nice guide! Short and sweet and to the point! One thing I am missing, as in all documentation I have found so far on VM, is something regarding fonts. I am not a very professional programmer, but I have been around since we made webpages in HTML on Notepad, and fonts have always been a pain in the ... to handle. Now, with WYSIWIG formatting it is pretty nice. On VM, however, the formatting you can do in the WYSIWIG editor is not that much. So to get the formatting correct, and in tune with the template you are using on Joomla, there is evidently some hacking needed. My guess is that this is pretty easy, but the file structure and the relationship between the different CSS and PHP files in Joomla and VM makes it complex to understand when you come in from the outside.
If you could add just a short paragraph about this in the guide, it would be sweet! After searching the forum for several days, I see that a lot of newbies and a few veterans run into trouble when it comes to formatting fonts, and many of these questions remain unanswered in the forum.
