I almost posted a link to the google search of "How To Make Fonts", but that's too smart ass. Though I would suggest googling (or other search engine) the phrase.
But to be fair, unless you have a set of programs such as Adobe Streamline, Macromedia Fontographer, and/or photoshop and other like programs to play with + the earlier mentioned Fontographer... you practically can't make a descent and professional font from what I've seen.
Though here is a link ((
FOUND HERE)) that will allow you to make a font online - I believe.
But it's pixel by pixel and
not the best program in the world... may be one of the crappier ones.
Good Luck!
