"And" Vs. "&" - Correct English Usage

I learned something new - the difference between the usage of word 'And' and the symbol '&'. I had no clue that they were different. So here's when to use 'And' and when to use '&'.

When you are connecting two nouns, you should use '&'. For example:

• #-Link-Snipped-# & #-Link-Snipped-# are moderators at CrazyEngineers.
• Jack & Jill went up the hill...

In all the other cases, you can safely use 'And'.

PS: 'And' can replace '&' anywhere.
