Couple of things. I've discovered
http://www.dkpsigs.com/, a site that allows you to make a custom WoW Signature, which I did, but i have been unable to get it to appear in the MacRumor Forums in my signature slot. They have links for URL to Sig, HTML, BBCode, but all of them appear as just a link, instead of a graphic in the signature. I'm wondering if MacRumors does not allow that feature?
Secondly, it's a lot of work to be a Tank.

I rejoiced when I got my Pally Tank up to 550 Defense, but when running Heroics, at times I'm providing a challenge to my healer to keep me going. I'm currently working on my Block, Parry, and Agility stats. The
Protection Pally Field Manual at Elitest Jerks is an outstanding document I'm using for reference. Any other suggestions? Thanks!
Here are my stats at
WoW Heros.
I'm sure this is no revelation for experienced players but if you are new to the game, Tank and Healer seem to be the two specs that require the most work and competence. A DPS spec is much more casual friendly.
