It's a much better system than having a few programmers without any real dumping expertise working in the shadows without really knowing what they're doing.
One thing that's clear from all the existing projects is that the dumpers are the ones who often really don't know what they're doing. My confidence in the console dumping scene is precisely 0. One of the things MESS will bring about is a place for real dumps to be documented, something which dumpers would have insisted on in the past if they had a higher level of integrity.
MESS is 'open', and anybody can contribute, as long as they provide sufficient evidence to back up their contributions. What MESS is *not* is a free-for-all of misinformation. If you can provide scans of things you've dumped that's obviously good and I'm sure genuine contributors will be granted access to SVN to add such details (but not to enforce their own 'no pirate dumps!!' style policies)
Now, if you could take your trolling elsewhere?
