I've been led to believe (based on what i've read) that HoU requires you have an existing character at least at a lvl 18 or so. I'd keep working on your vanilla and get thru chapter 2 of the OC or try to finish the first add-on. This is just hearsay, so don't fully quote me on that.
Better to be dead and cool than alive and uncool.
I don't believe in a lot of things, but I do believe in duct tape.
