Changing the word "Thread" to "Subject"

[nosaj]

My fellow Geeks,

In most Forums I see the word “Thread” used in place of the word “Subject”. However, the word thread is a Geek term. It is not an intuitive word for the average person or new forum user. As a result, it takes the average person or new user a little while to figure out that a thread is really a subject. However, everybody knows what a subject is, even a five year old. I would like to take the geeky terminology out of my forum. I would like to change the word thread to subject. I know I can hack my way through doing this as I myself am a Geek. But I was wondering if anyone had any ideas as to the most efficient way of doing this site wide.

A frustrated Geek,
Jason
