\ndifferent font families. Because your visitors may not have the same\
\nselection of fonts, you have the ability to pick a fall back scheme.\
\n\nSelect your first preference for a font face in the leftmost drop down,\
\nyour second in the next drop down, and so on.\
\n\nThe last option is a general font type, this allows your visitors computer \
\nto pick \"whatever\" font is registered as the default \"Serif\" font for example.";
