Nope, I still think they're dumb. Sure they're "valid" in the sense that if someone is given a name, that's their name, but they're not good names. They look bad and very silly. And I think making a "more name like counterpart" is unnecessary and ruins the point to using a word name in the first place. And if anyone actually used the name Mandalyn I'd roll my eyes for a thousand years. (Skye is different, it is also a place name. That's the reason for that spelling.) I can say "your opinion is wrong" just as well as you can, but I won't, because I know what an opinion is.
