This can used as a regular likebox too.
It has many options. You can move it around every corner of your site and has a couple of Facebook buttons to choose.
It is stylish with rounded corners by default.
Fully working with Joomla 2.5 and 3.0
"The module includes a Backlink to our site."
It is the only facebook likebox in slider position i found and asks only for my fanpage Url, no Api no time consuming methods.
It loads fast and it an excellent choice because it clearly uses Facebook Api and it will not stop working, like other Api developed module are.
