OK, "mor" is misspelled; it should be "môr" with the long o and the accent. This threw me off. "Môr" means "dark"
As for "maegla," the closest thing I found was "maegl" meaning "sharp".
So if I've translated it correctly, your name means "Sharp-Dark" but this doesn't make much sense.
I also found "magol" (I think the archaic form is "magl") which means "sword." So maybe you misspelled it, but I think you were aiming for "Dark Sword."
Am I right?
EDIT: Oh, crap! IS THIS QUENYA???? I THOUGHT IT WAS SINDARIN!!! NO WONDER I WAS THROWN OFF!!!
2nd EDIT: Oh, ok, this was Sindarin and the spelling was right; it was my interpretation that was wrong.
