I don't know about either? They used to be tied to how long you'd been on the forum, 020, 040, etc. not sure when it changed cause I never bothered with it. But pretty sure now you can make it what you want, just don't know how?
As for the roads, I only lived here in south MS for a year before I headed to Germany. Other than riding the Natchez or pine barrens I don't know any roads around here. Just got my bike back from Germany a week ago.
