I see the up-side of this but you have to remember, finishing fast is never a good idea. The more editors we get the more time we will have to spend going over their edits to make sure its all legit and not spam. This will take far longer than just us now finishing this wiki ourselves. Another point is that every new editor we get, we can give them a low-down personally which is what they would rather see. Oh whilst its nice to get some recognition every now and again, lets not get ahead of ourselves. Firstly lets finish this wiki then I can post advertisments on the forums for more editors.
That should get a few more editors here but not many, lots of people don't have the time or simply cannot be bothered.
