Hello I am trying to get my wordpress to allow underscores in the username. I have my site hosted on a provider I will not mention right now, but they are telling me that restriction came from upgrading to wordpress version 3.4 But I know that is not true because I have a site on godaddy which is 3.4.1 and I can have usernames with and underscore in them with no problem. So - can anyone here confirm what wordpress allows and doesn't as far as special characters? If you have this on a page already please just direct me there. thanks so much!
