First of all, if you pronounced LordSuragaha's name anything other than Sura-GAH-HAH when you first read it, you're wrong. > :c
Morgra was Morga. I still called her this well into her MIT training. I hope she doesn't notice or remember.
I still sometimes pronounce Sigyrn's name as Sigyn/SIG-IN.
Delija I called Deijah (DAY-ZHUH).
Most of these are more of my pronunciation than misspelling. There are many more, of which I cannot recall at the moment.
