So my name is taken as far as usernames and websites go so I want to replace the s in my last name with a z and just go by that. For example: Dave Herzberg instead of Dave Hersberg. (Not my real last name.)
Which then will give me… www.daveherzberg.com + usernames.
Will misspelling my name matter at all in terms of business?
It’s a business name. You can use whatever you like as long as it’s available.
