Help for commenting problems

I'd been having trouble commenting. Well, in fact, I was failing miserably to comment at all, so contacted the lovely "23 Things" help team. Jane Rawson (officially designated as having the patience of a saint:) ) sent the following replies which I thought might help other folk having difficulty.
The root of my woes, I discovered, was that I was using Explorer when I needed to be using Firefox. Here's Jane's helpful advice on this bit :-

"When you open up your internet from your desktop, is the icon you click on a blue "e" (Internet Explorer)or a red swooshy type thing (Firefox)? You should hopefully have both programs installed on your machine. If you're using Internet Explorer (with the blue 'e') then just close the program, and double-click on the Firefox icon (red swoosh) instead.

If you don't have both icons on your desktop, then open up your start menu (click on the start button on the toolbar in the bottom left of your screen) and look in your program list where hopefully they will both be listed."

My next problem was that I couldn't work out how to make my IGoogle page appear as my homepage on Firefox. Here's what to do:-

"You'll need to set iGoogle as your homepage on Firefox to make it show when you open it up. To do this, go to the 'Tools' menu and click on 'options'. In the box that opens, click on the 'General' tab. Type https://www.google.com/ig in the location box and click OK. You will probably need to sign in to iGoogle the first time, because Firefox doesn't 'know' you yet like Internet Explorer did, but you can ask it to remember you on sign-in for next time."

Yaay! I'm now commenting like a mad thing! Thanks Jane.
