Yea a community based pony data website I think would be pretty indestructable. I'm sure plenty of people would contribute PinkieMint, but how does one go about making one?
Something like that might work. It works like wikipedia, and I use a version of it as sort of a task manager for a project I have going on, but I have no clue how to set it up so that anyone *in the community* can add or subtract from it, much less without making it open to the rest of the cold cruel world to fiddle with and spam. And I also have no clue how to use it in a more sophisticated fashion than my own very very basic way, which would totally not be what a Pony-wiki would be.
Tell me if this sounds like what would work? It sounds like a combo of what DialgaBritesMom posted above and a full Wiki.
I created one it's called Ponypedia and to be added please just give me your e-mail and you can join! It's the free account which means we will have 2GB of media space so I'd keep the images down to a minimum, for instance if youre crating a page with info on a certain pony only add 1 pic of the pony for reference.
