I'm using this website to blog about concrete5 every now and then. It has an RSS feed to keep you updated. Haven't you heard of RSS? It's really fast and easy to use, I highly recommend it!

I also showcase add-ons I've made. Some of them are free, some of them are paid. But all of them are of high quality. There's probably some of them you'll like!
