OK, just to clear everything up for future posters, here is what Patchou has said
here is the following:
Most of the testing will be done by his friends on his MSN contact list.
If he needs more, he will let people that he knows at least a little test too. This means you must be a regular on the forums and will probably have done alpha testing for MP2.
If you're not on his contact list and want to test then you should email him at mplus@patchou.com - I very much doubt he will file through this now very long thread.
