you don't
Skuzzy has stated several times he will not "change" your Board ID. Imagine how many requests he would have daily of people wanting yo confuse others with a new name, or someone is embarrased by a post they did and want to hide from it, or anything.
If you want to go by a different name you have to make a new account. it is your choice if you stay open about your previous identity.
your "identity" here is defined by your CPID here. you may have heard people use the word "shades" that is someone going by a new name as to not be held accountable for their actions under another name. Basically you have accountability for the name wolfsnipe. If you want to start over that is your choice, but you would be starting over, 0 posts, new account.
