Don't think that I will sleep tonight. I am sure that the results will be of such enrichment that it will be a "Life Changing" event for me. Let's hope ImayKnow doesn't keep us in suspenders for tooooo long
After forty years, I can confidently say that 1 and 4 amount to the same thing. If you have a choice, start with 4. Option 1 is best left to those who don't think it makes any difference.
PS: 4 should always precede 1, NEVER the other way round!
Ah, but legally the first option could now include shirt lifters. So instead of there being six on this forum (still a disproportionately high number) there could be as many as fifteen (not sixteen because I know I'm not one!).
