Loading new fonts into FCP X

Hi all:

I have a client who wants three fonts that I just don't have. They are Rufina, Source Sans Pro & Rochester.

I knew how to do it years ago when I had a PC. and I think I remember doing it with Legacy, but I just don't know how to do it with X.

Can anyone help me with this?

warmly,
eric

Found out how to do it. All you have to do is open the Font Book in the Applications folder and then download the fonts that you want by hitting the + sign. I have Urban Fonts but that doesn't have the three fonts that my client wants so I'll have to keep searching. Adobe has Source Sans Pro, but it has like 15 different styles. Always a challenge!
