Hi Riya Welcome to the site!
I got your message about the posts.
This is exactly what posts are. You see; this is a forum, it's kind of like the bulletin boards in college and you "Post" messages on it so that everyone reads them and reply you back.
You have asked about Exjade, well there is a separate sub-forum about "Iron Chelation" on the main page and it contains different topics regarding Exjade. I hope that you will find the required information there; if not the you can ask everyone by posting it there.
