If you're using a computer to write in French, you may have run in to the difficulty of not knowing how to make the accent marks on the letters where they need to be. (Remember, they're important because they change the pronunciation so they're part of the spelling.)

On a PC computer:
You'll need to use the ALT key and a set of numbers on the number key pad.
....é
ALT + 130
....è
ALT + 138
....ê
ALT + 136
....ë
ALT + 137
....à
ALT + 133
....â
ALT + 131
....ä
ALT + 132
....ô
ALT + 147
....î
....ï
ALT + 140
ALT + 139
....ù
ALT + 150
....ç>>>
ALT + 135

On a Mac computer:
You'll need to use certain keys to get the accent and then type the letter you want under it.
