Exactly why this is the best forum on the internet, thank you guys.
I'm a bit of a novice about these things but am always glad to help out in anyway possible, including BBS searches. Below are the instructions on how to find old posts that don't show up in search results because they are over a year old. Texraid asked in a PM how to find Michaels old posts but here it is for all to use.
To search any forum go to Google and put in the sites home address, in this case
www.doublegunshop.com, then leave a space and put in your search term, in this case Petrov.
Usually the first result will show 3-4 posts and an option for "more results from www.doublegunshop.com". Clicking on that will bring up all the rest for you to sort through.
