Myabe you linked the wrong picture or something becasue I can't tell Jack from this picture....
I see something that looks like a big plastic bag on something...but can't really make anything else out...
Is there yeast at the bottom of the liguid OR Krauzen on top? If so then it is fine and you can pitch away...but based on that pic, I don't think anyone's gonna e able to help you.
A lot of us have commented that with stirplate on you don't really end up with krauzen on top....so if you have a layer of yeast in the bottom then you are ready to pitch that bad boy!!!
