JFBConnect Modules

In 5.0, the JFBC Follow module replaces the JFBC Subscribe module. It's functionality is about the same. It's meant to let you put a "Follow" button on your website. It refers to a specific Facebook *user* profile. When clicked, the visitor will then be 'following' the Facebook User profile specified so that the user's wall posts show up in their news feed. It's like being a friend, but it's a one-way connection.. the user doesn't need to approve the 'follow'.

Recommendations shows a full module with a list of recommendations. The Recommendations Bar shows a little 'tab' at the bottom of the page that pops up with recommendations. I can see how these could probably be explained better.

Your description of the Facebook Page integration is correct on each point. If you have any questions, let me know, but it sounds like you understand it.

Thanks,

- what are are functions that need or is better manage through Modules ?

It's completely site and need dependent. We try to provide the flexibility to do things how you want. Some suggestions are things like a "Like" button. That can be done in a module that's shown on every page of your site, or, if you have one special article that you want to really promote "Like'ing", you can put it directly in the center of the article.

The same goes for a comment box. Maybe you want it on all pages in a section. If so, a Module can work well for that to automatically add it. The {JFBCComments} tag can be good to add to one specific page (like an event, for example). The tag is also good if you want to create a template override for another extension and then add the tag exactly where you want it.

Since modules can only go in module positions, you can sometimes be limited as to where they can go, whereas a tag can go anywhere.

- what are Facebook functions/interacions that are useful to a website and what are superfluous/not essential ?

This is definitely site-dependent. Many users don't use the Like or even Login functionality, whereas other sites that's all they use. It really just depends on how you want to connect your site with Facebook. There aren't any modules/features I'd recommend *not* using in JFBConnect. The primary ones that many sites likely use are:
* Login
* Profile import
* Like buttons
* Comment boxes
* Fan module (to promote a Facebook Page)
* Open Graph Tags
Other popular features, but not as much as the above, are:
* Open Graph Actions
* Facebook Requests
The rest of the features are used on many sites, but probably not as commonly as the above.

I hope that helps,
Alex
