basic association

[writerone]

I am a computer knowledge deficient individual who needs basic information of 
doing things with my computer. I am currently running in Windows 7 and have 
installed Open Office which I use for basic typing where I print out what I 
type. No problem doing that, HOWEVER if I want to email what I type I am told 
that I must ASSOCIATE Open Office with my EMail Program (Windstream Mail) .  
dummy guy here doesn’t know HOW?    Help!!
