Well, there's Spiral Spy, The Equipment calculator thingy, etc.
I was thinking of copying Yppedia and having some stuff like this http://yppedia.puzzlepirates.com/Category:Third-party_tools
However I need some heads up about disclaimers about OOO not being responsible for anything and stuff like that.
It would basically adding a category and the pages for the tools. But from where do we link the category?. Should it be in the front page or what?
Also, a full list of tools and their webpages/etc would be appreciated from people who are aware from them, I have only followed Spiral Spy.
That sounds like an okay idea to me. You'd need a modified version of http://yppedia.puzzlepirates.com/Template:Third-party_tool to put at the top of each tool's page.
I'd have to think about where such a link would go. Actually for the first step I will check and see if there is going to be an official stance about third-party tools like on YPP.
