Hello everybody!   I would like to add another font when making a post or topic which is "Century Gothic" instead of changing the font name every time i want another font. Is there a way to do this?

Hello,

Go to Admin Panel >> Display >> Colors & Pictures >> Colors
and change the font to the one you want.

Hello,
 
I don't think there is an EASY way to add another font. But, you are able to change the one you have at any time.

Go here: Admin Panel >> Display >> Colors & Pictures >> Colors

Then simply change your font to the one you desire and save.

The only thing about this is that the font you change has to be on everyone's computer.  If you are trying to add a font that does not come with every computer system, you will have to add it some other way.
