Hello everyone, ♫♪

There were not many questions today but there were some good answers from CPhill, DragonSlayer554, AzizHusain and NinjaDevo. Thank you.

Today I referred an asker to a previous question that I pulled from NinjaDevo's new thread "Great answers to Learn from" Thanks Ninja.

It would be really good if all answerers made themselves very knowledgable about the contents of Ninja's 2 sticky threads. "Great answers to Learn from" and "Reference Material". They are invaluable and they should be used regularly. ♪ ♫

If you tell people that their answers are wrong then you need to tell them the correct answer.

This way they can work out why the answers are different and it may help both of you in the future.
