G-d is an English word indicating deity.
This word is derived first from Latin which, in its turn, derived from Greek as well. This word "God" was first invented in the greek version of the Bible "The Septuagint" from where the Latin and the English version are derived.

In the hebrew version of the Bible (Tanakh) the term G-d is translated with: Elohim, Adonai, El and YHWH.

Every God's name has it own different meaning. As I think we have lost a lot by incorporating all his names in one word (God) I think it is better to use the word G-d when needed instead using the uncensored version God.
I understand, now, that for you this is not the God's name but you'll never know who will be reading your thoughts so it is better to use the censored version (G-d) to respect the reader.
Hope this is clear enough.
Thank You
Oops! Sorry. In all the writing about all the different kinds of stuff, I missed your explanation of what G-d means. Well, Since G-d means God, why not just say God like the rest of us? I mean, it is enough trouble trying to figure out what people are saying without adding something that we are not used to.
EDIT: I went to both of those Wikipedia sites, and I couldn't find the word G-d anywhere. Did I spell it wrong? I used the small hyphen. Was I supposed to use the large one?
