Old Fogey new to Linux

Hello People,
Thank you for allowing me to make a contribution however small to this excellent community. I retired from an electronics manufacturer (SME) here in Nottingham, England some 6 years ago, and live peacefully with my wife Anne and our two cats in a village called Gunthorpe. I was the General Manager at my last business which manufactured Public Address & Alarm systems for installation in hazardous environments such as the oil and gas extraction industry, where there is an obvious risk of fire, or explosion. I have used computers all my life starting with MS-DOS and graduating through a mind boggling succession of Widows iterations throughout the years. In my early career in manufacturing industry in the 1970s I commissioned and purchased my first mainframe computer for use in the business for stock control, ledgers, payroll and SOP, POP etc. This of course was proprietary like IBM and I have never had any exposure to this mysterious Linux throughout my career.

I am very excited to have successfully installed Mint 19 as a dual boot with Win 10 PRO on a spare Dell Optilex 780 desktop and am looking forward to a great adventure as I learn more about it. I don't doubt that I will need some help from time to time, so please bear with me.
