Yes, we have many, though you will likely need to search for them.
You're more than welcome to start your own thread. If the question has been answered before it might get merged into an older thread, but it's not a big deal. We'd rather you just post than worry about if you're posting correctly and not posting at all.
Our in house search engine is quite poor, unfortunately.
I suggest going onto Google and searching our site this way:
bluelight.org: "your search here" <--- exactly like that with the quotes
typing that into google will bring you up results specifically from this site and is much better
