hinting 101

Hi all.

So I made a font, I put a lot of effort in it, looks good to me (printed).

But on screen it sucks!!! (ta na-na-na ta na-na)

Never hinted anything, don't know where to start? Is there any script, or other program that could help me with this? (I use really old mac)

I watched some videos, read some tutorials, so I made it here to see what you guys think.

Please don't link me with Fontlab video courses, they are great, but audio is really bad.

One more question, there is tons of diacritics, how to know to witch language they belong, and if that language has more diacritics I didn't do, so I would have a full set. Is there a way to know how many (and their names) languages does your font support?

Thanks
