I came a long way from different CMS and decided to switch to grav a few months ago. Best choice ever! I just completed to move all my content and my site is now up and running. As the webmaster of a voluntary fire brigade down in Austria I had to add a lot stuff of the last 5 years. Since nearly all of our visitors are using mobile devices I decided to use the Antimatter-theme and pimped it up by using some PHP-scripts and CSS-grids. Nearly all is written in plain-HTML (I love to have this option besides Markdown) using Notepad++ with the NppFTP-plugin.
Have a look at http://grav.ff-landegg.at (sorry, all in german language ;-)), feedback welcome!
Thanks to rhukster for helping me out so many times!
