Hi Everyone,

Along this thread, please try to take a minute each day or week and answer
one question on the site. We have a very good speed and contribution rate
already but there's always room for improvement.

It took longer than I expected but we now have 3 new close reasons for PCL,
OpenCV and Moveit Questions, which provide links to the recommended forums
for those topics. If you see these questions which should be asked on the
other forums please close using the appropriate reason.

And lastly if you have asked questions in the past and you have found the
solution or the problem is no longer relevant, please take a minute to
answer your own question, accept someone elses answer or even just close it
so we collectively don't spend time answering questions which don't need


PS David, organizing a sprint day to answer questions sounds great. I think
we've missed Talk Like a Pirate day, but maybe we can find another fun
