WPDevDesign is my go-to for Oxygen tutorials. Before I jump on Google or into any of my Oxygen FB groups with questions I always check WPDevDesign first because there’s a good chance Sridhar has already written a tutorial that addresses my needs. And if there isn’t, the WPDevDesign FB group is my next stop. Everyone on there is quick to respond with answers, ideas, and feedback. Plus, Sridhar and his top-class moderators are always around to weigh in and share their web/Oxygen development knowledge.
