That depends on the purpose of the server.
If you just want to sell your server with another tibia-like game, just copy what cipsoft do! Such as making a wiki page... The main purpose of global tibia is to get top level and have a bunch of friends to create a guild and take control (to rullz and make money). Spend time with "side quests" (because there's no real main quest) instead of getting level sounds like loose your precious time. Tibia quests are trully amazing and creative, but they are only a "coffee after lunch" or a "dessert" in the end...
The misterious of the global tibia are undoubtedly hard, it requires a lot of time to walk into a huge map with a lot of emptiness, caves with the only purpose is get level and quiet npc's with libraries without any good tip. If the main purpose of tibia was to seek these misterious, then a wiki page would sound like a "nintengo power" magazine, that teachs you how to finish the game. Sometimes, after trying so much to solve a puzzle, is better to give the awnser, or at least a tip, and this is better if is done by the game itself, not a web page, lol.
