Two quick things: Do we know Daario's age? And for the first time I wound up in a different-looking version of the forum, blue and white instead of beige and light blue, and the layout was different as well. This may be the wrong thread (don't know where else to ask, apologies) and a stupid question to boot, but forgive a noob his transgression(s) please cuz I was I able to use the Quote button in the blue-and-white version (for some reason I'm having trouble with it.) Help please :)
