As I have been on here I have found a lot of redundant posts on here. But at the same time a lot, a lot of good information here. So I decided to come up with this "guide" to help alleviate this problem. This is by no means all inclusive but should be close to a "one stop shop." If there is anything you would like added here, pm me and I will add it. Nothing listed here is in any particular order. Just the order I found them on the forums. This is a work in progress. I intend to add a new section for awhile. This should get quite extensive but should all be contained in a few posts.
Thanks goes to everybody that posted the excellent information on this forum and everybody that has posted links to information to add.
Please if I made any mistakes in this post please bring it to my attention and I will fix it promptly.
