I was refreshing my knowledge about placing signals by reading the tutorial done by Tim McIntosh (pikehkr) in the learning center, but part 5 and 6 are missing or are some where else. At the end of part 4 Tim was going show, in part 5, the results of the placings by hitting the Play button. Can any one tell me where these missing parts are? Thank you in advance, Herman.

Fixed.
I cleaned up the confusing items.
There are 2 series of tutorials.

Series 1 has the six basic tutorials (PT 1 - PT 6).
Series 2 is about blocking.

Note that these videos are hosted on Youtube. There is no guarantee they will be available forever.
if they are very important for you, grab them while you can.

Be lately: thank you. I am trying to find out when and how signals are flashing.
