The question 'where is chat' has come up a few times. This will explain that and will explain how to get to anywhere on the Island with a click. I remember trying to find it the first time myself and I needed help so this is for you if you need it too.
Additional note about logging into chat.
After clicking the chat link most times you get a page that has a message about "the moose outside shuda told ya" ... if you are already logged in, just refresh the page and Bob's your uncle. (You will be deposited in chat)
There are two ways to get to a chat link.
Here are directions using the transporter.
On the far left side of your screen there's a small-ish pink rectangle standing on it's end with five pictures on it starting with a bicycle at the top. The transporter.
Hover your mouse over the bicycle and the transporter's menu of rooms will drop down as in the picture below.
Sixth on the transporter menu is the link to chat.
The second way to get into chat is from the home page. It's easier using the transporter but you also might find it interesting when you're first looking around the island to check out each of the pictures. The first one is a 'Read me first' by our esteemed Unca Bobby. An interesting read. Check it out. Please. Scrolling down the pictures on the home page, the chat link is the picture of the dancing Peanuts charactors.
