Binh,
I still can't login to the page because of the extra inclusion of the Facebook Javascript at the end of the page. I can see you added an API key to JFBConnect, but the lower inclusion is overwriting the API key with nothing (blank), so the API key isn't getting set properly. Because of this, I can't login and help you with the Reconnect stuff much (I need to see it on your page first). Without looking, you may be able to add the following to your stylesheet and have some luck, but again, just can't guarantee anything without seeing it:
.fb_connect_user {
float: left;
font-size: 10px;
}
As for the Like module, Facebook has 3 different styles of buttons you can use: Standard, box-count and button-count. Viewing the faces of users is only available in the Standard mode. Also, the faces are only for the friends of the Facebook user, not all users who have liked the site. Unfortunately, Facebook does not allow you to change the "Be the first of your friends.." text, but setting the width of the module to the size of your sidebar will help it fit. Currently, the width appears to be set at 605px. I think you'll want to use something more like 200px.
As for setting the Like button in every thread of Agora, there's a few options. The first, and easiest, is simply to add a JFBCLike module and have it set to only display on your Agora menu item. This will cover the main forum index as well, but will cover all the pages like you're looking for. Harder, but more configurable, you could modify the Agora template to add {JFBCLike} wherever in the template you'd like. I don't know Agora's template files though, and you'd probably need to contact them for more information on how to do that.
Hope this helps. Email is the slowest method to get in touch with us. If you want more help with things, the forum is the best place to bring up questions, but we do respond to emails as they're received.
