Im looking for a free Social Networking component for Joomla.

There's a totally free version of 'Community builder' but each time i download .. the downloaded file is corrupted.

Any pointers permanently / easy to customize free 'social network' component for joomla Content management systems.

thanks ahead of time.

JomSocial is just like it will get which is free. You have to pay for this, but it's worth the investment. If by free you mean free, then you will find not good options apart from Community Builder.
