I find it easier to have a bunch of gold handy (if you can manage that, it depends on your situation) and just run around the noob zone. The more characters you play, the better. 5-Boxers have five signatures already on the app. You just need a few more sigs and you're good to go. The trick, at least the trick I use, is to offer a TON of gold to noob characters for sigs and let them know what's going on. They know to /gquit when the guild gets going and they get their gold. It's a pretty easy thing to do, really. Most people know the value of getting a few gold right off the bat, especially since at this point, people in the noob zones are rerolling from another server and would really love your gold. The best way to do this is just get five people that will do it quickly so they are in and out really soon. Less trouble for them, anyway.

That's the way I did it. If anyone knows a better way, please inform the rest of us - I'm considering changing the name of my boxer's guild which means I actually need to start a new guild.
