Chat Channel? Does it look like a chat channel? Check out how long i have been a member here.
As an old and illustrious member, I would think you'd have learned by now that it's impolite to bump your own thread less than two and a half hours after you created it. I can't imagine why replacing a mouse is that urgent. No, I do not think this looks like a chat channel; I was suggesting that perhaps you did. Nothing I've seen yet has made me reconsider that assumption.
Now, then, back on topic: What kind of mouse do you currently use? All mainstream mice are going to click, but if we knew what you were currently using we might be able to suggest something quieter which is readily available. However, if you want absolute silence from your mouse, there are two ways you can go. First, take a look at the link I posted earlier. If you're looking for the ultimate in mouse silence, you will definitely want to look at the mice covered in that review.
Second, you could take your current mouse apart and remove the clicking mechanism in the switches. In most microswitches like those used in mice, the click is independent from the switching action - it's actually a separate part, which can be removed by opening the switch housing. The switches aren't meant to be opened, so you'll have to carefully superglue them back together, but it's a cheap way to get a silent mouse.
