Finding Help

Hopefully, PMUG members and friends are gaining help when they need it.  Last week's update for Mac was an example of needing and finding help.  A quick email brought quick replies from David Passell, Art Gorski, and John Carter.  The technical details I didn't need; I just needed my printer to obey my commands. After following the suggestion to turn off the Firewall, since my Mac goes through a router, everything is fine.   Anyone else finding the help you need?  Want to pass the info along?
