I am plainly getting old (?) and not as computer literate as I thought. So I aplogise if this gets into the wrong area on this site!

First question: I have already posted a blog (SCALE CHANGE). I have since added an update to this but this does not seem to show up,separately, on the site. If you do click on the original blog it is there but, unless you click on the original blog, there seems to be no way that you would know. What am I doing wrong?

Second question: Where should I have posted this simple enquiry?????

All comments gratefully received......

Jim
