hi, thank you for your vote. I don't understand because Joomla 1.6 is no more supported and you should not use it. Anyway, if you had contacted me I would have sent to you an old version for 1.6 which is no more available on my website. But the menu is totally compatible 2.5 ;)
I reccomend to everyone, who looks for powerful pluging and integration for Facebook, to install your plugin.
Keep good working.
