Apparently, it’s the theme. This one (“Digg3”) only shows the name in uppercase and doesn’t show a tagline. I guess I’ll be diddling around with themes again. Darn.
EDIT: I think this one (“Connections”) will work. I’d rather it be blue than green, but I a) don’t know CSS, and b) don’t want to pay for the right to change it. So green it will be. The other option looks better visually, but you can’t use a custom header. And I want flamingos on my page! 😀
