I ran across a rather large Users Group on FaceBook of Pico and Z users. It was about 1000 members. However, I have searched and searched and cannot find it today.
There is already a big "Picobrew Pico users" thread here in this forum, all these Pico questions of yours should probably go in that thread they will be answered quicker. The group is called picobrewers.
As Jrb03 said above use the Picobrew Pico Users thread here in the Automated Brewing Forum. Lots of good information and many willing to help with questions if you don't plan on using facebook
