Power Leveling/Gold Guides

Hey guys, I was wondering if anyone has tried these power leveling and power gold guides that I hear about all the time? I���m kind of new to WoW, mainly b/c of it���s addictive nature, and really want to level up fast. I see these guides and claims of huge leveling in a small amount of time, but are they legit or will I get banned? I was looking at a site where a guy reviewed some guides,

bestwowguidesonline.com

but wanted to check with experienced players first.

Thanks!

after going through the leveling process once or twice for some people you know how to level fast and you get say about 5 levels per hour till 40 buuut since they changed the 20-60 to gain more exp from the quests and all that good stuff it may be faster, a friend of mine used joanasworld.com guide and leveled a hunter to 25 in like two three hours however i heard the hunter class is kinda an op leveling class and it's easy mode to solo stuff and what not, all in all i leveled one of each class to 10 and checked my /played and the priest had the longest /played... :/ so it's all class dependant really i guess also play skill dependant whatever the case my friend likes the joanasworld.com a bunch

I have used Joana's lvling guide in the past, and it is by far the best horde guide out there. the hunter and warlock class lvl the fastest because of the help from the pets/minions, but i started an undead rogue and using the guide, i lvled to 20 in 2 hours, my only advice is read the guide you are using once or twice before you start playing, and know step 4 and 5 before you get to step 1 and 2, if that makes any sense. if you have any questions about the guide ill be happy to help.
