Wow! Thank you everyone for your time in crafting the replies. You are all very helpful indeed. I do have a lot to read and am time poor in RL, but I'd try my best to catch up. Like what @Marianne Little said, I just "rose from the dead" and lo and behold, it's a whole new world! Once I'm caught up with my reading, can I ask questions here again pls? Thanks very much.
