I have been trying to change my usernames on my social channels from @Digiguru to my name and not been hugely successful. But I tried again today and added a hyphen between my name and to my surprise it was available. I then checked the company page I had recently setup and to my delight, it is also my name with a hyphen between. These are the new LinkedIn usernames for my profile http://linkedin.com/in/craig-jamieson and company http://linkedin.com/company/craig-jamieson
