Guild Wars 2

Hello, just here to let you guys at Anet know that I stumbled onto a way to glitch underneath the map of the obsidian sanctum. Dont want to blurt out how I did it, so im really just making this thread to ask how do I go about reporting this bug to staff, without letting the entire community know of its existence and the method to doing it.
