suggestion for improvement

I have 3 desktops, one laptop in my home business network. I’m using Network Magic Pro 5.0 and Speed Meeter Pro. I cannot find any simple, clear step-by-step instructions to set Comodo ver. 3.5.55810.432 so that all my computers will talk to each other. NM told me my problems are because I need to set Comodo correctly and sent me to a greatly outdated forum which was useless. The geek who wrote the directions for setting up Comodo Firewall used terms that don’t even exist on my version of Comodo. (:SAD)
So, my suggestion is that you tell me and NM where we can find these simple non-geek-talk directions and if they don’t really exist, create them and then tell the whole world and we will all love you! :BNC
PLEASE!
DO IT YESTERDAY!
THANKS!
