How to Chat in Freelancer?

I want to chat with the client on Freelancer. How can I do that? I am new to the platform and want to know if it is possible to chat with the client before accepting the project.

It is possible to chat with the clients on Freelancer. Once the person who posted the project accepts your bid, you can start chating with him from the right side of the screen. You can send him messages, files, and discuss the project details further in the chat window. But it is not possible to chat with anyone before accepting the project.
