I don't think it matters much.
I'm Stacey. Some people add an e, or they don't use it at all. Occasionally someone asks, "ie?" TBH, unless it's for official stuff, they can spell my name however they want.
DP's got a name which can have 1 of 3 different letters near the end. One option is more popular and common than the others, so he's always having to spell it out. I don't think he cares if people get it wrong either, except where he NEEDS it to be spelt properly.
People always think DD is Chantel instead of Chanel... or spell it some really hideous way... Schanelle or something. *vomit* It only bothers me when I correct them a thousand times and they still keep trying to use those horrible versions... it makes me wonder if they think I am THAT bogan that not only would I use a bit of a bogan name (I named her at 19... don't blame me! lol)... but that I'd slaughter the spelling to make it boganified even more.
