Thanks everyone for your replies!
Jordan, in the settings the ttf format isn't listed, I already looked at that

And I thought about your suggestion of making samples too, but I have too many fonts already and too little time...
I guess I'll have to download a font organiser then, though I'd prefer it if I could organise it all in one.
i started using Picasa a while back, and I think I'll just stick to it. I don't know if the keywords (tags) are kept with the files when you make a back-up on dvd though? Anyone know?
Thanks!
