That should get you started. I think I've covered all the basics enough for you to get equipped, join the Guild, and go start hunting some rats or frogs. If you need further help, ask around your guildmates. Most I know are willing to help out new recruits in our guild. You also might keep an eye out and go to a couple of Mentor meetings. These are usually announced good and loud all through the town, giving directions on where you can go to meet with a Mentor and ask some further questions. The Dragonrealms website is also full of different guides, both official and player written, to give you more tips and pointers. You can also post questions you have on the Dragonrealms message forums (forums.play.net) for more information still!

Good luck to you, guildmate, and congratulations on choosing the Barbarian Guild!
