Once you figure out how to do it, most of them are pretty easy, just the rush to build 30 marines/8tanks/10ghosts that have me scratching my head.. Always 15 seconds off from building my last ghost..
What you have to do is expo quickly and get 4 barracks. One to block (and initial marines), 1 with a reactor and 2 with tech labs. 1 Factory with tech lab is enough. You want to be constantly pumping units. Every building has to be constantly building units. One SCV has to be almost constantly building supply depots. And basically, that's it. Be careful of the mutalisks early on. You may lose one or two marines.
For Zerg covert mission, just use your roaches as decoys and your infestors to take control of the siege tanks and collossi, then just use these units to push forward to the main base and wipe out the scv's. Most of the challenges are pretty easy to get bronze in, it takes a bit of practise and experimentation to get silver and gold though.
I am working on getting access to the old news portal under a different URL for those that would rather use that for news before we get a different news view.
It is OK though for the main page to open up on the forum in the view it was before. As long as the portal has its own URL so it can be viewed that way I do want to try it as a regular forum view for a while
I switched it to a "Standard" article forum. This will show the thread list like normal, but the threads themselves will have the first post set up above the rest of the "comments"
