Ok for the question. Where are my horses? I had the war-barbed cavalry horses on most of my characters but I don't find any of them. I didn't upgrade to gold membership yet btw, I wanted to look around a bit first. But not on foot thank you very much. lol
Press your C key. You now have a 'Mount' tab, "Currency" (tokens) tab and several others. The mount will be there. Drag it to the empty space and click on the saddle icon to activate it.
