Oh thank you, Rouge - I've just read them. That was a great help. I suppose it is a bit tough when you start and you don't know much about all the different products. I guess it is just trial and error. Thank goodness for this site!
You're welcome Lydia. It is daunting but I have to say I have learned an amazing amount from this site.
By the way, the Search facility on here is really useful, I don't know if you've come across it yet. Click on the Search button on the menu bar at the top and a box comes up for you to fill in. I usually can find the info I'm looking for using that. Have a play with it!
