What is posted on DAC is also posted on FB as far as the CAG is concerned. However there are many posts that come out on DAC from other members who are not posting of FB anymore. So the answer is yes and no : D . You will get duplicates, but you will also get different info from other ceramic posters.
Make sure you join the CAG group within this great site. To do that just click on GROUPS, then click on CAG, then click on "Join Grop" in upper right corner. Ceramics are so much fun, they are truly the 3-dimensional canvas. Have a GREAT day! your friend and fellow artist Tommy Lee
