I now have a profile on Google+, where I'm "Brian Gill." That's my name, although my signature reads "Brian H. Gill."
I'd prefer to use "Aluwir," since that's how quite a few folks know me online - and there's only one "Aluwir" that I know of: while there's a surprising number of Brian Gills out there. Including, for a while, someone who was in the same line of work that I was. He's probably still in that career: I've moved along.
And that's another topic.
