How to report an Issue?

I have found a bug on bonita 6.3.1, a simple way to reproduce it and I need it fix!

Unfortunately I am not able to add an issue on "atlassian" because the button just doesn't show up! i tried to register with exactly the same mail and exact same info than here but nothing.

Anyway this is the problem... THE EXAMPLE: Step 1 and step 2 start at the begining, Step 3 needs Step 1 and Step 2 finished Step 4 needs only step 1 Step 5 needs Step 3 and Step 4 finished
