In this section are links to support the information in the chapters above. Any serious effort to master World of Warcraft will require you to become familiar with these web sites.
All Purpose Links
These links are great for everything: questing, crafting, making gold, even getting maps of zones and instances.
http://thottbot.com/
Some people consider Thottbot the best WOW web site out there. You enter a search term (name, item, quest, zone; spell it right!) and you'll get info on that item. Even better, other players usually have entered comments about how, where, or what worked for them. (Beware of the occasional bit of rough language.)
http://www.wowwiki.com/
Where Thottbot is more of an item database, WOWwiki is more of an encyclopedia. Like any 'wiki', WOWwiki is user updated; anyone can create or update an entry. The search engine is more forgiving than Thottbots. Generally, WOWwiki gives you the big picture while Thottbot supplies greater detail. Also, WOWwiki will have lore information for those of you who like the back story to the game.
http://wow.allakhazam.com/
Allakhazam is much like Thottbot. Many WOW players like it better for the layout and navigation.
http://www.wowhead.com/
WOWhead is another WOW database web site. You can search for items you are interested in, and read comments from other players.
Crafting Links
The previous web sites are great for helping you locate crafting information. The web sites in this section are even better for crafting. They go into more detail.
http://wow.crafterstome.com/home.html
Recipes lists, crafting guides, and more can be found at Crafter's Tome.
http://www.lootables.com/
Lootables offers guides, item search, and more.

PVP Links
It's a great idea to look up techniques and strategies for PVPing. Here's a list of sites that'll give you the knowledge to go along with your gear and buffs to rule in PVP.
http://shadowpanther.net/
Despite the name, the above site is great for Rogues. Twinking your Rogue is covered here in great detail.
http://www.pvpscene.com/
The player forums of PVP Scene are a great source for PVP strategies by class, with a lot of attention paid for Arena contests.
Official WOW ForumsOfficial WOW ForumsOfficial WOW ForumsOfficial WOW Forums
The official WOW forums feature a forum devoted to PVP playing. This is a great place to read what others say, and to post questions of your own.
Bring your thick skin to the forums. There's plenty of jerks there, as well as many friendly and helpful players.
Gold-Making Links
The secrets to making gold are not-so-secret. We've discussed the worthwhile secrets already in this guide. If someone claims to be able to make a thousand gold in a day, they are either Auction House masters, or lying. And the thing about the Auction House is: you have to do the background work to get stuff to put in there! So even if you can turn hundreds of gold a day, you still have to work hours and hours to get your materials.
For gold making tips online, many of the sites we've already mentioned are great. For example, WOWwiki lists the vendor prices of most items. You can check out any items you aren't familiar with and find out who uses it for what, and how much it vendors for. Then, armed with this knowledge, check the prices and quantities in the Auction House for the item and set your prices accordingly.
WOWwiki also lists routes you can run for Mining and Herbalism.
One of the best WOW blogs, www.wowinsider.com quite often touches on these topics. WOW insider is worth checking out every day. Quite often PVP strategies, crafting tips, or gold-making secrets are discussed in their columns.
