Silly IPlayUOTOOMuCH...surely you know if we told you we'd have to kill you...and because this is Siege, res kill, dry loot you, and kill your little dog too!
Just curious, by "one man island" do you mean Dot Island? If so, that is not a secret...it is in every T-hunter rune library.
You might try as a start, compiling a Siege-specific list of all the password triggered teleporter spots in the world, giving coordinates, description, where they go, maybe screenies of the trigger object. While stuff like the Malas Secret spots & rune pouch locations & the Moonglow teleporters are easy to find on Stratics for example, others of these teleporters are NOT easy to find info about. Also some of them might not be old, just abandoned event junk. People who have been playing a long time and/or do a lot of events & in-game quests likely can contribute a lot to such a project.

P.S. missed homegrown's mention of the "rats" teleporter. That is a nice one, and the kind of example I meant...just a friendly warning, I have it on good authority that someone uh, may have peed in the only source of fresh water there at the beach.
