That link is one of the reasons I came on here too. I bought my GP and loved it to the point I ended up dumping tons of money and time into it. I may not have had as much money into it as others here, but I do have a 34 page build thread that puts the amount of time in perspective.
I love this forum. The guys here are great and we have a few very knowledgeable ones who have been there and done that. If you need any help, try the search bar first, then feel free to make a post if you can't find what you're after. Welcome again, and I hope you enjoy your time with GPF.
