Lets get cracking!

Let's change that.

In preperation for our planned Dire Maul West and North runs I have some recommended reading.

North:

Read up, gear up and get ready to rumble

We'll need some frost oil and a Thorium widget for the tribute run.
Can anyone provide? (Frost oil we might have covered, the widget is abit more sticky, pun intended)

I think multiple gordok tribute runs might be insane to gather shards and such. We should think about pooling the resources of a few guild members, going on a few (we'll see how hard they are) and then collectively sell and get the profit. Think about it and see if you'd wanna be in on it.
