You're gonna open a new account because your friends are having a hard time finding your hub?
You know you can view your hub, copy paste the link, and just give it directly to all your friends.
But anyway, if you open a new account it will not affect your old account. However you will have to unpublish your old hub if you want to republish it on your new account. And there's no easy way to transfer hubs (that I know of) so you will probably need two browsers to be able to do an easy copy paste of your old hub's stuff.
