I guess there is a misunderstanding here.
I will be testing 3.0 in our env and can report my findings here, but
I don't quite understand how would you like to participate.
Anyone is able to get the latest milestone build from the atlassian's
site and test it. Besides, our test environment is not accessible from
the public internet, so you wouldn't be able to see anything.
Did I miss something?
cheers,
Igor
