Just wondering if people like signing their work as their full name or their signature name. I think I prefer C.M.E Harvey instead of Chantelle Harvey, but can initials be a bit of a mouthful?
Some of the biggest authors in the world sign their work with initials - J. K. Rowling, J R R Tolkien, C.S. Lewis, George R R Martin.
It's personal.
In my opinion, Chantelle is a lovely name, and unusual. Why lessen it? I could be wrong, but I can't think of too many writers going by that name.
I think most people change their name when they are famous, or about to be, or just plain don't like their name, or need a new identity, to escape past misdemeanors.
As a writer, there might be some gain in changing your name.
But ultimately, it will be your writing that gets you noticed.
It's a personal choice of whether to use a pseudo name of various workings of your initials or Christian names. I don't believe it's a big issue, but if it was necessary I would be guided by the publisher.
JK Rowling borrowed her mothers initial, as the publishers didn't believe that a book about a boy wizard by Joanne Rowling would appeal to boys. Essentially JK was used to 'Tolkienify' her name for wider appeal.
Did it make a difference? No idea, and we will never know.
Chantelle, honestly, I would say submit your work in the name you feel most comfortable. Personally, I hope that one day bookshelves will be stocking the books by 'A S Glenn'.
