I shall begin by giving you a 4 letter word. And what you need to do is to reply to the latest thread by changing 1 letter of the given word to make another word, and then changing the letter of that new word to another letter to make yet, another new word. Like a word ladder. One rule is that you cannot add letters, so it should always be 4 letters long.
So for example, I give you the word PING, and then someone will reply and say the word PONG, and then someone will go on to say SONG, and so on. Let's see how long we can keep this going....
The word I am giving you is:
TICK
