Hi Barb, I suspect that you're probably joking around a bit (hopefully with all of us) the same as I usually do...but because I'm (hopefully unnecessarily) paranoid that I might come off as insulting with people who don't know me very well yet, and just in case on the possible chance that anyone ever mis-interprets my intentions...maybe I had better take some time to put in here that I SINCERELY hope that you, or anybody else, NEVER takes anything I suggest or write as questioning any of anybody's abilities - in fact quite the opposite - because I consider this forum as a non-judgemental "information pot" where everyone contributes whatever information their experience, skills, trial & errors, and/or even what they read or heard might help. And adding in the joking around makes for a truly magical and special place.
I consider myself to have been fortunate enough to experience a wide and varied background in mechanics, electronics, computers, and networks - (my father used to joking call it "jack of all trades, master of none") - but I have learned through the years that regardless how much or little experience, it just scratches the surface of each field, and I encounter people almost each and every day who know so much more than I do about so many more things in those same and other fields than I ever could hope to know. It's when everyone's knowledge is combined that it becomes truly valuable.
So...if by any chance you (or anyone else) took (or take) any of my posts (now or in the future) as questioning any of your abilities, you have my sincere apologies. My only desire is to share and contribute something possibly worthwhile, which I see others do seemingly effortlessly on a daily, even hourly, basis (and I have no illusion that I'm not more wrong than right more often than not since every situation has possible combination differences)...and it's sincerely NEVER my intention to possibly come off as arrogant - which I've personally experienced is always an unintentional risk.
In fact, with what you listed as background and my background of getting into computers by building my first one because they weren't common yet (I consider humorous, but dates me as well), I'll bet we could have one heck of a fun conversation some time!
