You could start the thread.

That's probably a better option than signatures as it's a lot less intrusive for those of us who quite frankly don't give one about people's music tastes or youtube videos.

IIRC the signatures were pretty basic - just 1-2 lines of smallish text. As long as there was an option for people to turn signatures on and off when they view threads, it might not be a bad thing to have. I'm personally hoping for a "first unread post" button, though. :p

I've created the thread, although I suspect that quite a lot of people who purchase games on GOG would go on to make a walkthrough or Let's Play on YouTube to bring the game to prominence on the site :/

Since I've gotten the answers I needed and a solution has been provided, this thread can be closed now. :)
