If you present your case for a name change that is valid then I am sure the moderators that be would consider a name change (or deleting your old posts)...
If running for office and you don’t want your comments to used as ammunition against you Jim might let change (or delete).
If using your real name has you in fear of being punished it is possible.
I am not a mod, never even played one on TV. Take my post w/ a grain of salt.
OH, I do not want a name change, I am eastforker, with a little bit of web detective you can find our where I live, phone number and many other things. I am me and all the garbage that goes with it.
