I bought a beautiful theme from Lexington a couple weeks ago. I didn't know Astro at the time, but Michael helped me get set up and really went above and beyond with his support. Now I'm happily redoing my site to look gorgeous with his template.

I love your Astro themes and have a few sites in the works. I'd like to find ways to increase the use of Astro because I love it so much. Thanks for saving me so much time in dev work.
