Font Colour Selection Help please.

[chocoholic]

As you can see, I'm rather fond of "Georgia" font, size 2 and colour blue and I like to use it for all my postings.

At the moment I'm selecting it manually every time I post a message.

Is there any way of keeping it as a permanent selection so that I don't have to choose it again each time I post?

(Sorry if this is an obvious question but I'm a bit of a novice at this computing lark!)
