>>13221610Haha you're in for a fun(?) time then.
To be honest, unless the surname ends up having some important role you can usually go without mentioning it at all without any issues.
Yeah, you're better off doing that.
Typos aren't really a big deal in the early stages, so long as you go back and proofread before you post the finished story (which you should always do anyway).
Good luck!
