I am going to start posting sites that use Mango Blog so that people can see it running "in the wild". If you would like me to post yours, just let me know. I will post them as I find them, but if for any reason you don't want me to list yours, let me know and I'll remove it from the list.
The first one is my own website, AsFusion.
I just added a new skin called "Happy Blog". Original design is by Luka Cvrk
It requires version Alpha 1.4.9 or above. Enjoy!
