TemplatePlazza have just released a new Joomla theme called SocioPlazza.
As the name, SocioPlazza is designed with a social networking website style and is more than suitable suitable for Joomla websites with Community Builder component installed.
This template is equipped with a suckerfish horizontal dropdown menu and a collapsible tabbed module position with cookie function.
We really like the colours and you might also. Have a look here as they're also releasing something else today.
